Subject: [PATCH] ASoC: cs35l56: Call pm_runtime_dont_use_autosuspend()
Date: Fri, 8 Sep 2023 11:17:16 +0100	[thread overview]
Message-ID: <20230908101716.2658582-1-rf@opensource.cirrus.com> (raw)

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().

THIS WON'T APPLY CLEANLY TO V6.5 AND EARLIER:
We will send a separate backported patch to stable.
