Subject: [PATCH] media: st-delta: Fix PM disable depth imbalance in delta_probe
Date: Wed,  5 Jan 2022 11:55:15 +0000	[thread overview]
Message-ID: <20220105115515.12196-1-linmq006@gmail.com> (raw)

The pm_runtime_enable will increase power disable depth.
If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable().

Fixes: f386509 ("[media] st-delta: STiH4xx multi-format video decoder v4l2 driver")
