Subject: [PATCH] media: st-hva: Fix PM disable depth imbalance in hva_hw_probe
Date: Wed, 5 Jan 2022 11:31:03 +0000 [thread overview]
Message-ID: <20220105113104.7783-1-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: 57b2c06 ("[media] st-hva: multi-format video encoder V4L2 driver")
