+Subject: ALSA: hda/hdmi: Fix incorrect mutex unlock in silent_stream_disable()
+
+The silent_stream_disable() function introduced by the commit
+b1a5039759cb ("ALSA: hda/hdmi: fix silent stream for first playback to
+DP") takes the per_pin->lock mutex, but it unlocks the wrong one,
+spec->pcm_lock, which causes a deadlock. This patch corrects it.

-Subject: drm/amd/display: Add get_dig_frontend implementation for DCEx
-
-Some old ASICs might not implement/require get_dig_frontend helper; in
-this scenario, we can have a NULL pointer exception when we try to call
-it inside vbios disable operation. For example, this situation might
-happen when using Polaris12 with an eDP panel. This commit avoids this
-situation by adding a specific get_dig_frontend implementation for DCEx.
