[PATCH AUTOSEL 6.3 33/67] ASoC: SOF: sof-client-probes: fix pm_runtime imbalance in error handling

[Sasha Levin]

From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>

[ Upstream commit bc424273c74c1565c459c8f2a6ed95caee368d0a ]

When an error occurs, we need to make sure the device can pm_runtime
suspend instead of keeping it active.
