2012-07-30[media] Avoid sysfs oops when an rc_dev's raw device is absentDouglas Bagnall
For some reason, when the lirc daemon learns that a usb remote control has been unplugged, it wants to read the sysfs attributes of the disappearing device. This is useful for uncovering transient inconsistencies, but less so for keeping the system running when such inconsistencies exist. Under some circumstances (like every time I unplug my dvb stick from my laptop), lirc catches an rc_dev whose raw event handler has been removed (presumably by ir_raw_event_unregister), and proceeds to interrogate the raw protocols supported by the NULL pointer. This patch avoids the NULL dereference, and ignores the issue of how this state of affairs came about in the first place. Version 2 incorporates changes recommended by Mauro Carvalho Chehab (-ENODEV instead of -EINVAL, and a signed-off-by).

2012-05-20[media] ati_remote: add regular up/down buttons to Medion Digitainer keymapAnssi Hannula
There are many different Medion X10 remotes that need slightly different keymaps. We may not yet have all the needed keymaps, in which case a wrong keymap may be used. This happened with Medion X10 OR2x remotes before the keymap for them was added, causing the ati_remote driver to select the Medion Digitainer keymap instead. Unfortunately, the Medion Digitainer keymap doesn't have the standard X10 up/down scancodes assigned to KEY_UP and KEY_DOWN keycodes, making wrongly assigned remotes mostly unusable. Add the regular KEY_UP and KEY_DOWN scancodes to the Medion X10 Digitainer keymap, making any Medion remote mostly usable even when wrongly used with that keymap (standard buttons, such as up/down/left/right, 0-9, play/stop/pause, have the same scancode in all the X10 remotes).

An early registration of an ISR was causing a crash to several users (for example, with the ite-cir driver: http://bugs.launchpad.net/bugs/972723). The reason was that IRQs were being triggered before a driver initialisation was completed.

2012-04-11[media] ati_remote: add support for Medion X10 Digitainer remoteAnssi Hannula
Add support for another Medion X10 remote. This was apparently originally used with the Medion Digitainer box, but is now sold separately without any Digitainer labeling. A peculiarity of this remote is a scrollwheel in place of up/down buttons. Each direction is mapped to 8 different scancodes, each corresponding to 1..8 notches, allowing multiple notches to the same direction to be transmitted in a single scancode. The driver transforms the multi-notch scancodes to multiple events of the single-notch scancode. (0x70..0x77 = 1..8 notches down, 0x78..0x7f = 1..8 notches up) Since the scrollwheel scancodes are the same that are used for mouse on some other X10 (ati_remote) remotes, the driver will now check whether the active keymap has a keycode defined for the single-notch scancode when a mouse/scrollwheel scancode (0x70..0x7f) is received. If set, scrollwheel is assumed, otherwise mouse is assumed. This remote ships with a different receiver than the already supported Medion X10 remote, but they share the same USB ID. The only difference in the USB descriptors is that the Digitainer receiver has the Remote Wakeup bit set in bmAttributes of the Configuration Descriptor. Therefore that is used to select the default keymap. Thanks to Stephan Raue from OpenELEC (www.openelec.tv) for providing me both a Medion X10 Digitainer remote+receiver and an already supported Medion X10 remote+receiver. Thanks to Martin Beyss for providing some useful information about the remote (including the "Digitainer" name). This patch has been tested by both of them and myself.

This patch removes BUG_ON in ir_raw_event_thread which IMO is a over-kill, and this kills the ir_raw_event_thread too. With a bit of additional logic in this patch, we nomore need to kill this thread. Other disadvantage of having a BUG-ON is, wake_up_process(dev->raw->thread) called on dead thread via ir_raw_event_handle will result in total lockup in SMP system. Advantage of this patch is ir-raw event thread is left in a usable state even if the fifo does not have enough bytes.

2012-03-08[media] media: ir-sony-decoder: 15bit function decode fixJames Hogan
The raw Sony IR decoder decodes 15bit messages slightly incorrectly. To decode the function number, it shifts the bits right by 7 so that the function is in bits 7:1, masks with 0xFD (0b11111101), and does an 8 bit reverse so it ends up in bits 6:0. The mask should be 0xFE to correspond with bits 7:1 (0b11111110). The old mask had the effect of dropping the MSB of the function number from bit 6, and leaving the LSB of the device number in bit 7.

2012-03-08[media] rc/ir-raw: use kfifo_rec_ptr_1 instead of kfifoJames Hogan
Raw IR events are passed to the raw event thread through a kfifo. The size of the event struct is 12 bytes, and space for 512 events is reserved in the kfifo (6144 bytes), however this is rounded down to 4096 bytes (the next power of 2) by __kfifo_alloc(). 4096 bytes is not divisible by 12 therefore if the fifo fills up a third of a record will be written in the end of the kfifo by ir_raw_event_store() because the recsize of the fifo is 0 (it doesn't have records). When this is read by ir_raw_event_thread() a corrupted or partial record will be read, and in the case of a partial record the BUG_ON(retval != sizeof(ev)) gets hit too. According to samples/kfifo/record-example.c struct kfifo_rec_ptr_1 can handle records of a length between 0 and 255 bytes, so change struct ir_raw_event_ctrl to use that instead of struct kfifo.

2012-01-26[media] imon: don't wedge hardware after early callbacksJarod Wilson
This patch is just a minor update to one titled "imon: Input from ffdc device type ignored" from Corinna Vinschen. An earlier patch to prevent an oops when we got early callbacks also has the nasty side-effect of wedging imon hardware, as we don't acknowledge the urb. Rework the check slightly here to bypass processing the packet, as the driver isn't yet fully initialized, but still acknowlege the urb and submit a new rx_urb. Do this for both interfaces -- irrelevant for ffdc hardware, but relevant for newer hardware, though newer hardware doesn't spew the constant stream of data as soon as the hardware is initialized like the older ffdc devices, so they'd be less likely to trigger this anyway... Tested with both an ffdc device and an 0042 device.

2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
