[PATCH v3 3/5] scsi: ufs: Release clock if DMA map fails

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

 



From: Can Guo <cang@xxxxxxxxxxxxxx>

In queuecommand path, if DMA map fails, it bails out with clock held.
In this case, release the clock to keep its usage paired.
