Subject: [PATCH] ASoC: allo-piano-dac-plus: Fix volume limit locking
|
|
|
|
Calling snd_soc_limit_volume from within a kcontrol put handler seems
|
|
to cause a deadlock as it attempts to claim a write lock that is already
|
|
held. Call snd_soc_limit_volume from the main initialisation code
|
|
instead, to avoid the recursive locking.
|
|
|
|
See: https://github.com/raspberrypi/linux/issues/6527
