[PATCH 2/2] mmc: queue: Flush recovery work on cleanup

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

 



To prevent any recovery work running after the queue cleanup flush it.
Any recovery running post-cleanup dereferenced mq->card as NULL
and was not meaningful to begin with.
