From 4db8e14ce478e5086e5811488c6dcb25e0cf9583 Mon Sep 17 00:00:00 2001 From: Miaoqian Lin Date: Wed, 5 Jan 2022 10:41:09 +0000 Subject: [PATCH] drm/bridge: Add missing pm_runtime_disable() in __dw_mipi_dsi_probe [ Upstream commit 96211b7c56b109a52768e6cc5e23a1f79316eca0 ] If the probe fails, we should use pm_runtime_disable() to balance pm_runtime_enable(). Add missing pm_runtime_disable() for __dw_mipi_dsi_probe.
