From 395829c61a196a0821a703a49c4db3ac51daff73 Mon Sep 17 00:00:00 2001 From: Miaoqian Lin Date: Mon, 7 Mar 2022 09:16:37 +0100 Subject: [PATCH] media: atmel: atmel-isc: Fix PM disable depth imbalance in atmel_isc_probe The pm_runtime_enable will decrease power disable depth. If the probe fails, we should use pm_runtime_disable() to balance pm_runtime_enable().
