[PATCH 1/2] spi: Add missing pm_runtime_put_noidle() after failed get

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If pm_runtime_get_sync() fails we should call pm_runtime_put_noidle().
This is probably not a critical fix as we should only hit this when
things are broken elsewhere.
