2016-11-23ALSA: usb-audio: Add quirk for Syntek STK1160Marcel Hasler
[ Upstream commit bdc3478f90cd4d2928197f36629d5cf93b64dbe9 ] The stk1160 chip needs QUIRK_AUDIO_ALIGN_TRANSFER. This patch resolves the issue reported on the mailing list (http://marc.info/?l=linux-sound&m=139223599126215&w=2) and also fixes bug 180071 (https://bugzilla.kernel.org/show_bug.cgi?id=180071).

Although a similar issue was spotted and a fix patch was merged in commit [6b760bb2c63a: ALSA: timer: fix division by zero after SNDRV_TIMER_IOCTL_CONTINUE], it seems covering only a part of iceberg. In this patch, we fix the issue a bit more drastically. Basically the continue of an uninitialized timer is supposed to be a fresh start, so we do it for user timers. For the direct snd_timer_continue() call, there is no way to pass the initial tick value, so we kick out for the uninitialized case.

2016-10-05ALSA: timer: Call notifier in the same spinlockTakashi Iwai
[ Upstream commit f65e0d299807d8a11812845c972493c3f9a18e10 ] snd_timer_notify1() is called outside the spinlock and it retakes the lock after the unlock. This is rather racy, and it's safer to move snd_timer_notify() call inside the main spinlock. The patch also contains a slight refactoring / cleanup of the code. Now all start/stop/continue/pause look more symmetric and a bit better readable. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Sasha Levin <alexander.levin@verizon.com>
2016-10-04ALSA: fireworks: accessing to user space outside spinlockTakashi Sakamoto
[ Upstream commit 6b1ca4bcadf9ef077cc5f03c6822ba276ed14902 ] In hwdep interface of fireworks driver, accessing to user space is in a critical section with disabled local interrupt. Depending on architecture, accessing to user space can cause page fault exception. Then local processor stores machine status and handles the synchronous event. A handler corresponding to the event can call task scheduler to wait for preparing pages. In a case of usage of single core processor, the state to disable local interrupt is worse because it don't handle usual interrupts from hardware. This commit fixes this bug, performing the accessing outside spinlock. This commit also gives up counting the number of queued response messages to simplify ring-buffer management.

Although the notification itself is mostly harmless, it may potentially be harmful, and should be suppressed. Actually some components PCM may free ctl elements during the disconnect or free callbacks, thus it's no theoretical issue.

2016-07-12ASoC: ssm4567: Reset device before regcache_sync()Lars-Peter Clausen
[ Upstream commit 712a8038cc24dba668afe82f0413714ca87184e0 ] When the ssm4567 is powered up the driver calles regcache_sync() to restore the register map content. regcache_sync() assumes that the device is in its power-on reset state. Make sure that this is the case by explicitly resetting the ssm4567 register map before calling regcache_sync() otherwise we might end up with a incorrect register map which leads to undefined behaviour. One such undefined behaviour was observed when returning from system suspend while a playback stream is active, in that case the ssm4567 was kept muted after resume.

2016-07-12ALSA: timer: Use mod_timer() for rearming the system timerTakashi Iwai
[ Upstream commit 4a07083ed613644c96c34a7dd2853dc5d7c70902 ] ALSA system timer backend stops the timer via del_timer() without sync and leaves del_timer_sync() at the close instead. This is because of the restriction by the design of ALSA timer: namely, the stop callback may be called from the timer handler, and calling the sync shall lead to a hangup. However, this also triggers a kernel BUG() when the timer is rearmed immediately after stopping without sync: kernel BUG at kernel/time/timer.c:966! Call Trace: <IRQ> [<ffffffff8239c94e>] snd_timer_s_start+0x13e/0x1a0 [<ffffffff8239e1f4>] snd_timer_interrupt+0x504/0xec0 [<ffffffff8122fca0>] ? debug_check_no_locks_freed+0x290/0x290 [<ffffffff8239ec64>] snd_timer_s_function+0xb4/0x120 [<ffffffff81296b72>] call_timer_fn+0x162/0x520 [<ffffffff81296add>] ? call_timer_fn+0xcd/0x520 [<ffffffff8239ebb0>] ? snd_timer_interrupt+0xec0/0xec0 .... It's the place where add_timer() checks the pending timer. It's clear that this may happen after the immediate restart without sync in our cases. So, the workaround here is just to use mod_timer() instead of add_timer(). This looks like a band-aid fix, but it's a right move, as snd_timer_interrupt() takes care of the continuous rearm of timer.

snd_usb_add_audio_stream() call [ Upstream commit 836b34a935abc91e13e63053d0a83b24dfb5ea78 ] create_fixed_stream_quirk(), snd_usb_parse_audio_interface() and create_uaxx_quirk() functions allocate the audioformat object by themselves and free it upon error before returning. However, once the object is linked to a stream, it's freed again in snd_usb_audio_pcm_free(), thus it'll be double-freed, eventually resulting in a memory corruption. This patch fixes these failures in the error paths by unlinking the audioformat object before freeing it.

Note that on s3c64xx, the pl08x DMA data is already a pointer, but gets cast to resource_size_t so we can pass it as a resource, and it then gets converted back to a pointer. In contrast, the data we pass for s3c24xx is an index into a device specific table, and we artificially convert that into a pointer for the filter function.

[ Upstream commit 2f80b2958abe5658000d5ad9b45a36ecf879666e ] This quirk allows us to avoid the noisy: current rate 0 is different from the runtime rate message every time playback starts. While USB DAC in the RR2150 supports reading the sample rate, it never returns a sample rate other than zero in my observation with common sample rates.

2016-04-18ALSA: hda - Fix regression of monitor_present flag in eld proc fileHyungwon Hwang
[ Upstream commit 023d8218ec0dfc30e11d4ec54f640e8f127d1fbe ] The commit [bd48128539ab: ALSA: hda - Fix forgotten HDMI monitor_present update] covered the missing update of monitor_present flag, but this caused a regression for devices without the i915 eld notifier. Since the old code supposed that pin_eld->monitor_present was updated by the caller side, the hdmi_present_sense_via_verbs() doesn't update the temporary eld->monitor_present but only pin_eld->monitor_present, which is now overridden in update_eld(). The fix is to update pin_eld->monitor_present as well before calling update_eld(). Note that this may still leave monitor_present flag in an inconsistent state when the driver repolls, but this is at least the old behavior. More proper fix will follow in the later patch.

[ Upstream commit 0ef21100ae912f76ed89f76ecd894f4ffb3689c1 ] The Microsoft HD-5001 webcam microphone does not support sample rate reading as the HD-5000 one. This results in dmesg errors and sound hanging with pulseaudio.
