Subject: [PATCH] media: exynos4-is: Fix PM disable depth imbalance in fimc_is_probe
Date: Mon,  7 Mar 2022 07:52:06 +0000	[thread overview]
Message-ID: <20220307075206.10737-1-linmq006@gmail.com> (raw)

If probe fails then we need to call pm_runtime_disable() to balance
out the previous pm_runtime_enable() call.

Fixes: 9a761e436843 ("[media] exynos4-is: Add Exynos4x12 FIMC-IS driver")
