[PATCH v3 18/24] media: ti-vpe: cal: Remove DMA queue empty check at start streaming time

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

 



The vb2 queue ensures that the start streaming operation will only be
called with a minimal number of buffers queued to the driver. There's
thus no need to manually check if the DMA queue is empty. Remove the
check.
