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().
Signed-off-by: Richard Fitzgerald rf@opensource.cirrus.com Fixes: 2a930a6da8ec ("ALSA: hda/cs35l56: Add driver for Cirrus Logic CS35L56 amplifier")
Applied now. The Fixes tag points to a non-existing ID, so I corrected in my side to 73cfbfa9caea.
thanks,
