[PATCH] [v2] spi: tegra114: Fix runtime PM imbalance on error
From: Dinghao Liu
Date: Sat May 23 2020 - 08:58:09 EST
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.
