From 550e68ea36a6671a96576c0531685ce6e6c0d19d Mon Sep 17 00:00:00 2001 From: Dinghao Liu Date: Fri, 22 May 2020 17:51:39 +0800 Subject: [PATCH] mtd: rawnand: gpmi: Fix runtime PM imbalance on error pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. Thus a pairing decrement is needed on the error handling path to keep the counter balanced.
