From d4f5a095daf0d25f0b385e1ef26338608433a4c5 Mon Sep 17 00:00:00 2001 From: Navid Emamdoost Date: Mon, 15 Jun 2020 00:49:28 -0500 Subject: [PATCH] drm/exynos: fix ref count leak in mic_pre_enable in mic_pre_enable, pm_runtime_get_sync is called which increments the counter even in case of failure, leading to incorrect ref count. In case of failure, decrement the ref count before returning.
