[PATCH] ALSA: hda: cs35l56: Call pm_runtime_dont_use_autosuspend()
Posted by Richard Fitzgerald 2 years, 3 months ago
Driver remove() must call pm_runtime_dont_use_autosuspend().

Drivers that call pm_runtime_use_autosuspend() must disable
it in driver remove(). Unfortunately until recently this was
only mentioned in 1 line in a 900+ line document so most
people hadn't noticed this. It has only recently been added
to the kerneldoc of pm_runtime_use_autosuspend().

Applied now.
The Fixes tag points to a non-existing ID, so I corrected in my side
to 73cfbfa9caea.


thanks,
