[PATCH 5.13 694/800] ASoC: rt5682: Fix a problem with error handling in the io init function of the soundwire

[Greg Kroah-Hartman]

From: Oder Chiou <oder_chiou@xxxxxxxxxxx>

[ Upstream commit 9266d95405ae0c078f188ec8bca3a004631be429 ]

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

Fixes: 867f8d18df4f ('ASoC: rt5682: fix getting the wrong device id when the suspend_stress_test')
