6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Cristian Ciocaltea <cristian.ciocaltea@xxxxxxxxxxxxx>
[ 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().
Fixes: 1873ebd30cc8 ("ALSA: hda: cs35l41: Support Hibernation during Suspend")
