From 7dcfb327f8fd7418124fc6d63bdce91b5844f50a Mon Sep 17 00:00:00 2001 From: Dinghao Liu Date: Thu, 21 May 2020 08:27:45 +0200 Subject: [PATCH] media: staging: tegra-vde: fix runtime pm imbalance on error pm_runtime_get_sync() increments the runtime PM usage counter even the call returns an error code. Thus a pairing decrement is needed on the error handling path to keep the counter balanced.
