[PATCH v2 10/11] ALSA: hda: cs35l41: Undo runtime PM changes at driver exit time

From: Cristian Ciocaltea
Date: Thu Sep 07 2023 - 13:25:48 EST


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().

Fixes: 1873ebd30cc8 ("ALSA: hda: cs35l41: Support Hibernation during Suspend")
