From a68e06e729b1b06c50ee52917d6b825b43e7d269 Mon Sep 17 00:00:00 2001 From: Dinghao Liu Date: Thu, 9 Jul 2020 14:43:56 +0800 Subject: PCI: rcar: Fix runtime PM imbalance on error pm_runtime_get_sync() increments the runtime PM usage counter even when the call returns an error code. Thus a corresponding decrement is needed on the error handling path to keep the counter balanced.
