Subject: [PATCH 6.5] ASoC: cs35l56: Call pm_runtime_dont_use_autosuspend()

commit ec03804552e9a723569e14d2512f36a8e70dc640 upstream

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().

Backport note: This is the same change as the upstream
commit but the cs35l56->base.dev argument in the upstream
code is cs35l56->dev in older releases.
