[PATCH] [v2] spi: tegra20-slink: Fix runtime PM imbalance on error

[Dinghao Liu <dinghao.liu@xxxxxxxxxx>]

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.

Changelog:

v2: - Use pm_runtime_put_noidle() instead of pm_runtime_put().
