Subject: [PATCH] ASoC: rt5682: Fix a problem with error handling in the io init function of the soundwire
Git-commit: 9266d95405ae0c078f188ec8bca3a004631be429
Patch-mainline: v5.14-rc1
References: git-fixes

The device checking error should be a jump to pm_runtime_put_autosuspend()
as done before returning value.
