[PATCH 5.10 210/452] media: exynos4-is: Fix PM disable depth imbalance in fimc_is_probe
From: Greg Kroah-Hartman
Date: Tue Jun 07 2022 - 13:41:44 EST
From: Miaoqian Lin <linmq006@xxxxxxxxx>
[ Upstream commit 5c0db68ce0faeb000c3540d095eb272d671a6e03 ]
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")
