[PATCH] dmaengine: tegra210-adma: fix pm_runtime_get_sync failure

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

 



Calling pm_runtime_get_sync increments the counter even in case of
failure, causing incorrect ref count. Call pm_runtime_put if
pm_runtime_get_sync fails.
