ALSA: hda - Fix headset mic detection problem for two dell machines

2016-08-20T16:11:01+00:00

commit 59ec4b57bcaede46546d54d037a21004b9aa5cef upstream. One of the machines has ALC255 on it, another one has ALC298 on it. On the machine with the codec ALC298, it also has the speaker volume problem, so we add the fixup chained to ALC298_FIXUP_SPK_VOLUME rather than adding a group of pin definition in the pin quirk table, since the speak volume problem does not happen on other machines yet.

ALSA: hda/realtek - Can't adjust speaker's volume on a Dell AIO

2016-08-20T16:11:01+00:00

commit dd9aa335c88003d131ac874e7f6809902de0b847 upstream. We have a Dell AIO on which we can't adjust its speaker's volume. The problem is it is connected to a Audio Output node without Amp-out capability. To fix it, we change it to be connnected to a node with Amp-out capability.

ALSA: hda: Fix krealloc() with __GFP_ZERO usage

2016-08-20T16:11:01+00:00

commit 33baefe5e72f17a6df378e48196cd8cada11deec upstream. krealloc() doesn't work always properly with __GFP_ZERO flag as expected. For clearing the reallocated area, we need to clear explicitly instead. Reported-by: Joe Perches Signed-off-by: Takashi Iwai Signed-off-by: Greg Kroah-Hartman

ALSA: usb-audio: Fix quirks code is not called

2016-07-18T10:32:45+00:00

snd_usb_{set_interface,ctl_msg}_quirk checks chip->usb_id to need calling a quirks code. But existed code path that not calling dev_set_drvdata in usb_audio_probe.

ALSA: hda: add AMD Stoney PCI ID with proper driver caps

2016-07-12T10:23:55+00:00

This allows the device to correctly show up as ATI HDMI rather than a generic one and allows the driver to use the available caps. Signed-off-by: Awais Belal Cc: Signed-off-by: Takashi Iwai

ALSA: hda - fix use-after-free after module unload

2016-07-11T18:07:46+00:00

register_vga_switcheroo() sets the PM ops from the hda structure which is freed later in azx_free. Make sure that these ops are cleared. Caught by KASAN, initially noticed due to a general protection fault.

ALSA: pcm: Free chmap at PCM free callback, too

2016-07-08T07:15:44+00:00

The chmap ctls assigned to PCM streams are freed in the PCM disconnect callback. However, since the disconnect callback isn't called when the card gets freed before registering, the chmap ctls may still be left assigned. They are eventually freed together with other ctls, but it may cause an Oops at pcm_chmap_ctl_private_free(), as the function refers to the assigned PCM stream, while the PCM objects have been already freed beforehand. The fix is to free the chmap ctls also at PCM free callback, not only at PCM disconnect. Reported-by: Laxminath Kasam Cc: Signed-off-by: Takashi Iwai

ALSA: ctl: Stop notification after disconnection

2016-07-08T07:15:44+00:00

snd_ctl_remove() has a notification for the removal event. It's superfluous when done during the device got disconnected. 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. This patch adds the check of card->shutdown flag for avoiding unnecessary notifications after (or during) the disconnect. Cc: Signed-off-by: Takashi Iwai

ALSA: hda/realtek - add new pin definition in alc225 pin quirk table

2016-07-08T06:44:19+00:00

We have some Dell laptops which can't detect headset mic, the machines use the codec ALC225, they have some new pin configuration values, after adding them in the alc225 pin quirk table, they work well. Cc: Signed-off-by: Hui Wang Signed-off-by: Takashi Iwai
