ALSA: hda: cs35l41: Undo runtime PM changes at driver exit time
[ Upstream commit 85a1bf86fac0c195929768b4e92c78cad107523b ]
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().
