Subject: spi: tegra114: Fix runtime PM imbalance on error
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cddc36f3fd706b1046a4d4608359c0003f72db32;p=linux.git

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.
