Subject: [PATCH] media: ti-vpe: cal: Remove DMA queue empty check at start
streaming time
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.
