[PATCH 1/8] [media] au0828: Cancel stream-restart operation if frontend is disconnected

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

 



From: Changbing Xiong <cb.xiong@xxxxxxxxxxx>

X-Patchwork-Delegate: mchehab@xxxxxxxxxx
If the tuner is already disconnected, It is meaningless to go on doing the
stream-restart operation, It is better to cancel this operation.
