[PATCH] [v2] PCI: qcom: Fix runtime PM imbalance on error

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

 



pm_runtime_get_sync() increments the runtime PM usage counter even
it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced.
