ALSA: hda - Fix path power activation

2015-08-25T05:59:02+00:00

The widget power-saving code tries to turn up/down the power of each widget in the I/O paths that are modified at each jack plug/unplug. The recent report revealed that the power activation leaves some widgets unpowered after plugging. This is because snd_hda_activate_path() turns on path->active flag at the end of the function while the path power management is done before that. Then it's regarded as if nothing is active, and the driver turns off the power. The fix is simply to set the flag at the beginning of the function, before trying to power up.

ALSA: hda - Check all inputs for is_active_nid_for_any()

2015-08-25T05:59:01+00:00

The is_active_nid_for_any() function in the generic parser is supposed to check all connections from/to the given widget, but the current code checks only the first input connection (index = 0). This patch corrects the code to check all inputs by passing -1 to index argument. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=102521 Cc: [v4.1+] Signed-off-by: Takashi Iwai

ALSA: hda: fix possible NULL dereference

2015-08-24T13:02:03+00:00

After a for-loop was replaced by list_for_each_entry, see Commit bbbc7e8502c9 ("ALSA: hda - Allocate hda_pcm objects dynamically"), Commit 751e2216899c ("ALSA: hda: fix possible null dereference"), a possible NULL pointer dereference has been introduced; this patch adds the NULL check on pcm->pcm, while leaving a potentially superfluous check on pcm itself untouched.

ALSA: hda - Shutdown CX20722 on reboot/free to avoid spurious noises

2015-08-21T08:28:00+00:00

On shutdown/reboot of CX20722, first shut down all EAPDs, then shut down the afg node to D3. Failure to do so can lead to spurious noises from the internal speaker directly after reboot (and before the codec is reinitialized again, i e in BIOS setup or GRUB menus).

ALSA: hda - Fix the white noise on Dell laptop

2015-08-13T05:56:44+00:00

Dell laptop causes the white noise by login screen and headphone, and the fixup function ALC292_FIXUP_DISABLE_AAMIX can eliminate this noise.

ALSA: hda - Fix MacBook Pro 5,2 quirk

2015-07-30T20:30:29+00:00

MacBook Pro 5,2 with ALC889 codec had already a fixup entry, but this seems not working correctly, a fix for pin NID 0x15 is needed in addition. It's equivalent with the fixup for MacBook Air 1,1, so use this instead.

ALSA: hda - Fix race between PM ops and HDA init/probe

2015-07-29T17:37:26+00:00

PM ops could be triggered before HDA is done initializing and cause PM to set HDA controller to D3Hot. This can result in "CORB reset timeout#2, CORBRP = 65535" and "no codecs initialized". Additionally, PM ops can be triggered before azx_probe_continue finishes (async probe). This can result in a NULL deref kernel crash. To fix this, avoid PM ops if !chip->running. Signed-off-by: U.
