ASoC: cs35l41: Undo runtime PM changes at driver exit time
[ Upstream commit 2d5661e6008ae1a1cd6df7cc844908fb8b982c58 ]
According to the documentation, drivers are responsible for undoing at
removal time all runtime PM changes done during probing.
Hence, add the missing calls to pm_runtime_dont_use_autosuspend(), which
are necessary for undoing pm_runtime_use_autosuspend().
Note this would have been handled implicitly by
devm_pm_runtime_enable(), but there is a need to continue using
pm_runtime_enable()/pm_runtime_disable() in order to ensure the runtime
PM is disabled as soon as the remove() callback is entered.
