From cddc36f3fd706b1046a4d4608359c0003f72db32 Mon Sep 17 00:00:00 2001 From: Dinghao Liu Date: Sat, 23 May 2020 20:57:04 +0800 Subject: [PATCH] spi: tegra114: 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.
