Subject: [media] bttv: fix querycap and radio v4l2-compliance issues

The querycap ioctl didn't support V4L2_CAP_DEVICE_CAPS and the radio device
implemented audio and video inputs and s_std, which are not part of the radio
API.

Subject: [media] bttv: disable g/s_tuner and g/s_freq when no tuner present,
 fix return codes

If no tuner is present, then disable the tuner and frequency ioctls.
We can remove a number of checks from those ioctls testing for the presence
of a tuner.
Also remove some tuner type checks (now done by the core) and fix an
error return when the prio check fails.
Finally some 'unlikely' statements are removed since those only make sense
in tightly often executed loops, otherwise they just clutter up the code.

Subject: [media] bttv: fix field handling inside TRY_FMT

- don't return -EINVAL for invalid field types, handle those as if it
  was FIELD_ANY.
- the handling of FIELD_SEQ_BT/TB was wrong as well: if such field formats
  aren't supported, then fall back to FIELD_ANY instead of returning an error.

Subject: [media] bttv: convert to the control framework

Note that the private chroma agc control has been replaced with the standard
CHROMA_AGC control.
Also fixes a mute/automute problem where closing the file handle would force
mute on. That's not what you want since that would make the mute state out of
sync with the mute control. Instead check against the user count.

Probe for additional tvaudio devices, and allow tvaudio+tda7432 to
co-exist. My STB TV PCI FM bttv card has a tda7432, a tda9850 and a
tea6420 and with this patch it finally works again (probably for the
first time in many years).

Subject: [media] bttv: do not switch to the radio tuner unless it is accessed

Just opening the radio tuner should not cause a switch to the radio tuner.
Only after calling g/s_tuner or g/s_frequency should this happen.
This prevents audio being unmuted as soon as the driver is loaded because
some process opens /dev/radioX just to see what sort of node it is, which
switches on the radio tuner and unmutes audio.
This code can be improved further by actually keeping track of who owns the
tuner and returning -EBUSY if switching tuner modes will cause problems.
But for now just fix the annoying case where on boot the radio turns on
automatically.

Subject: [media] bttv: remove g/s_audio since there is only one audio input

Note that the current driver does not implement enumaudio (so apps cannot
tell that audio inputs are present), it does not set V4L2_CAP_AUDIO, nor
does it set audioset when calling ENUM_INPUT. And G_AUDIO doesn't set the
stereo flag either. So these g/s_audio ioctls are quite pointless and
misleading. Especially since some surveillance boards do not have audio
at all.

Subject: [media] cx25821: Cleanup filename assignment code

I'm pasting the original code and my proposal on the commit message for
make it easy to compare the two versions.
Line 62 of cx25821-audio-upstream.h contains:
char *_defaultAudioName = "/root/audioGOOD.wav";
Original code after replace kmemdup for kstrdup, and after fix return error
code:
if (dev->input_audiofilename) {
	dev->_audiofilename = kstrdup(dev->input_audiofilename,
				      GFP_KERNEL);
	if (!dev->_audiofilename) {
		err = -ENOMEM;
		goto error;
	}
	/* Default if filename is empty string */
	if (strcmp(dev->input_audiofilename, "") == 0)
		dev->_audiofilename = "/root/audioGOOD.wav";
} else {
	dev->_audiofilename = kstrdup(_defaultAudioName,
				      GFP_KERNEL);
	if (!dev->_audiofilename) {
		err = -ENOMEM;
		goto error;
	}
}
Code proposed in this patch:
if ((dev->input_audiofilename) &&
    (strcmp(dev->input_audiofilename, "") != 0))
	dev->_audiofilename = kstrdup(dev->input_audiofilename,
				      GFP_KERNEL);
else
	dev->_audiofilename = kstrdup(_defaultAudioName,

if (!dev->_audiofilename) {

 control
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are cases where we want to call audio_mux() without changing the value of
the v4l2 mute control, for example
- mute mute on last close
- mute on device probing

We can't and do not save the mute setting in function audio_mux(), so we
should also not save the input in this function for consistency.

Subject: [media] bttv: apply mute settings on open
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously, this has been done implicitly for video device nodes by calling
set_input() (which calls audio_input() and also modified the mute
setting).
Since input and mute setting are now untangled (as much as possible), we need to
apply the mute setting with an explicit call to audio_mute().
Also apply the mute setting when the radio device node gets opened.

Subject: [media] v4l2: pass std by value to the write-only s_std ioctl

This ioctl is defined as IOW, so pass the argument by value instead of by
reference. I could have chosen to add const instead, but this is 1) easier
to handle in drivers and 2) consistent with the s_std subdev operation.

Subject: [media] ivtv: prepare ivtv for adding const to s_register

The ivtv_itvc function receives a pointer to v4l2_dbg_register. When we
add const to that pointer in the s_register case we will run into a problem
here since this common function would discard const in that case. So
change this function so it receives the address and a pointer to a value.
In addition we now set the size field in the g_register function which is
where it belongs.
This will simplify the next patch where const will be added to s_register.

Subject: [media] demux.h: Remove duplicated enum

"enum dmx_ts_pes" and "typedef enum dmx_pes_type_t" are just the
same enum declared twice, since Kernel (2.6.12). There's no reason
to duplicate it there, and sparse complains about that:
	drivers/media/dvb-core/dmxdev.c:600:55: warning: mixing different enum types
So, remove the internal define, keeping just the external one.
Internally, use only "enum dmx_ts_pes", as it is too late to drop
dmx_pes_type_t from the userspace API.

Subject: [media] cx88: kernel bz#9476: Fix tone setting for Nova-S+ model
 92001

Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal
polarisation. According with the info provided at the BZ, model
92002 does.

The difference is that, on model 92001, the tone select is done via
isl6421, while, on other devices, this is done via cx24123 code.
This patch adds a way to override the demod's set_tone at isl6421
driver. In order to avoid regressions, the override is enabled
only for cx88 Nova S plus model 92001. For all other models and
devices, the set_tone is provided by the demod driver.

Patch originally proposed at bz@9476[1] by Michel Meyers and
John Donoghue but applying the original patch would break support
for all other devices based on isl6421.

Subject: [media] tuner-core: Change config from unsigned int to void *

config looks like a hack that was added to tuner-core to allow some
configuration of TDA8290 tuner (it's not used by any other driver).
But with the new configuration options of tda8290 driver (no_i2c_gate
and std_map), it's no longer sufficient.
Change config to be void * instead, which allows passing tuner-dependent
config struct to drivers.
Also update saa7134 driver to reflect this change (no other driver uses this).

Subject: [media] tda8290: change magic LNA config values to enum

Use enum instead of magic values for LNA config in tda8290.
Update tda827x, tda18271 and saa7134 to use the enum too.

Subject: [media] cx25821: do not expose broken video output streams

The cx25821 driver has support for one audio output channel and two video
output channels.
This is implemented in a very ugly and very evil way through a custom ioctl
that passes the filename of a file containing the video data, which is then
read by the driver itself using vfs.
There are a number of problems with this:
1) it's very ugly and very evil (I can't say that often enough).
2) V4L2 supports video output, so why not use that?
3) it's very buggy, closing the filehandle through which you passed the ioctl
   will oops the kernel.
4) it's a nasty security leak since this allows you to load any file in the
   system as a video or audio source, so in theory you can output /etc/passwd
   to audio or video out and record & decode it on another device.
Because of all these issues we no longer register those output video nodes.

Subject: [media] cx25821: the audio channel was registered as a video node

Skip the audio channel when registering the video nodes. This fixes a bug
where that incorrectly registered 'video' node was never unregistered.
Note: this bug only surfaces if the video output nodes are enabled again
after the previous patch disabled them.

drivers/media/pci/cx25821/cx25821-video.c: In function ‘cx25821_video_register’:
drivers/media/pci/cx25821/cx25821-video.c:518:1: warning: the frame size of 1600 bytes is larger than 1024 bytes [-Wframe-larger-than=]
Fixed by just making the struct video_device template static const.

Subject: [media] cx25821: remove bogus radio/vbi/'video-ioctl' support

This device does not support radio or vbi, so remove anything referring
to that.
In addition, the driver created an 'video ioctl' node, which was unused and
was effectively identical to the first video node.
This bogus video node is now removed, leaving us with 8 video capture nodes
and 2 video output nodes.

Subject: [media] cx25821: remove unused fields, ioctls

Do some spring cleaning:
- there are no board defines with tuners, so remove bogus tuner support.
- tv standard handling has nothing to do with tuners, so keep that.
- replace the deprecated current_norm by g_std.
- querystd isn't implemented, so remove the ioctl.
- remove a bunch of unused fields in cx25821.h

Subject: [media] cx25821: fix log_status, querycap

log_status shouldn't print LOG STATUS lines, the core does that already.
Fix querycap version number and add device_caps support.

Subject: [media] cx25821: remove unnecessary global devlist

This device list is not necessary. The kernel already has all that information,
so just use that instead.
Also remove a bogus refcount and some dead 'private_free' code in the alsa driver.

Subject: [media] cx25821: embed video_device, clean up some kernel log spam

Embed the video_device struct instead of allocating it.
Remove some of the annoying and ugly kernel messages shown during
loading and unloading of the module.

Subject: [media] cx25821: replace resource management functions with fh
 ownership

Just remember which filehandle is streaming instead of using complicated
resource masks.
After this patch we can replace cx25821_fh with v4l2_fh.

Subject: [media] cx25821: switch to v4l2_fh, add event and prio handling

It is now possible to remove cx25821_fh and replace it with v4l2_fh,
which in turn makes event handling and core prio handling possible.

No idea why these custom ioctls exist: they have perfectly normal v4l2

Subject: [media] cx25821: remove references to subdevices that aren't there

This driver does not have subdevices, so why call subdev ops? After
removing that it became apparent that only Composite is supported as
input, so remove also any reference to other inputs.

using standard ioctls.
The next step will be to provide a proper write() interface.

Subject: [media] cx25821: drop cx25821-video-upstream-ch2.c/h

cx25821-video-upstream_ch2.c/h is practically identical to cx25821-video-upstream.c/h
so add support for ch2 into cx25821-video-upstream.c instead.
After this we can replace the custom ioctls with a proper write() interface.

Subject: [media] cx25821: remove cx25821-audio-upstream.c from the Makefile

The audio output is currently not used as this should be rewritten as an
alsa driver. For the time being remove this source from the Makefile.

Subject: [media] cx88: Fix unsafe locking in suspend-resume

Legacy PCI suspend-resume handlers are called with interrupts enabled.

But cx8800_suspend/cx8800_resume and
cx8802_suspend_common/cx8802_resume_common use spin_lock/spin_unlock
functions to acquire dev->slock, while the same lock is acquired in the
corresponding irq-handlers: cx8800_irq and cx8802_irq.

That means a deadlock is possible if an interrupt happens while suspend
or resume owns the lock. The patch replaces spin_lock/spin_unlock with
spin_lock_irqsave/spin_unlock_irqrestore.

Found by Linux Driver Verification project (linuxtesting.org).

Subject: [media] cx25821-alsa: get rid of a __must_check warning

The hole reason for __must_check is to not ignore an error.

However, a "ret" value is used at cx25821 just to avoid the
Kernel compilation to compain about it.

That, however, produces another warning (with W=1):

drivers/media/pci/cx25821/cx25821-alsa.c: In function 'cx25821_audio_fini':
drivers/media/pci/cx25821/cx25821-alsa.c:727:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable]

With the current implementation of driver_for_each_device() and
cx25821_alsa_exit_callback(), there's actually just one
very unlikely condition where it will currently produce
an error: if driver_find() returns NULL.

Ok, there's not much that can be done, as it is on a driver's
function that returns void, but it can at least print some message
if the error happens.

Subject: [media] cx88: make core less verbose

Along the time, several debug messages were added at cx88-cards.
While those are still useful to track some troubles with
tuners, they're too verbose:
[ 5768.281801] cx88[0]: Calling XC2028/3028 callback
[ 5768.287388] cx88[0]: Calling XC2028/3028 callback
[ 5768.292575] cx88[0]: Calling XC2028/3028 callback
[ 5768.299408] cx88[0]: Calling XC2028/3028 callback
[ 5768.306244] cx88[0]: Calling XC2028/3028 callback
...

and, most of the time, useless.

So, disable them, except if core_debug modprobe parameter
is used.
