[PATCH AUTOSEL 4.9 07/23] ASoC: dpcm: allow start or stop during pause for backend

[Sasha Levin]

From: 이경택 <gt82.lee@samsung.com>

[ Upstream commit 21fca8bdbb64df1297e8c65a746c4c9f4a689751 ]

soc_compr_trigger_fe() allows start or stop after pause_push.
In dpcm_be_dai_trigger(), however, only pause_release is allowed
command after pause_push.
So, start or stop after pause in compress offload is always
returned as error if the compress offload is used with dpcm.
To fix the problem, SND_SOC_DPCM_STATE_PAUSED should be allowed
for start or stop command.

[PATCH AUTOSEL 4.9 09/23] ASoC: Intel: atom: Take the drv->lock mutex before calling sst_send_slot_map()

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 81630dc042af998b9f58cd8e2c29dab9777ea176 ]

sst_send_slot_map() uses sst_fill_and_send_cmd_unlocked() because in some
places it is called with the drv->lock mutex already held.

So it must always be called with the mutex locked. This commit adds missing
locking in the sst_set_be_modules() code-path.

[PATCH AUTOSEL 4.9 21/23] ALSA: ice1724: Fix invalid access for enumerated ctl items

[Sasha Levin]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit c47914c00be346bc5b48c48de7b0da5c2d1a296c ]

The access to Analog Capture Source control value implemented in
prodigy_hifi.c is wrong, as caught by the recently introduced sanity
check; it should be accessing value.enumerated.item[] instead of
value.integer.value[].  This patch corrects the wrong access pattern.

[PATCH AUTOSEL 4.9 22/23] ALSA: hda: Fix potential access overflow in beep helper

[Sasha Levin]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit 0ad3f0b384d58f3bd1f4fb87d0af5b8f6866f41a ]

The beep control helper function blindly stores the values in two
stereo channels no matter whether the actual control is mono or
stereo.  This is practically harmless, but it annoys the recently
introduced sanity check, resulting in an error when the checker is
enabled.

This patch corrects the behavior to store only on the defined array
member.
