2014-05-25[media] v4l: vb2: Add a function to discard all DONE buffersLaurent Pinchart1-0/+24
When suspending a device while a video stream is active all buffers marked as done but not dequeued yet will be kept across suspend and given back to userspace after resume. This will result in outdated buffers being dequeued. Introduce a new vb2 function to mark all done buffers as erroneous instead, to be used by drivers at resume time.

2014-05-25[media] omap3isp: Cancel all queued buffers when stopping the video streamLaurent Pinchart1-0/+2
When stopping a video stream the driver waits for ongoing DMA opeations to complete for the currently active buffer, but doesn't release the non-active queued buffers. This isn't a problem in most cases as the video device is usually closed after the stream is stopped, which will release all the buffers. However the problem would generate a warning when switching to videobuf2. Fix it by cancelling all buffers after DMA operations have completed.

2014-05-24[media] media: stk1160: Avoid stack-allocated buffer for control URBsEzequiel Garcia2-2/+9
Currently stk1160_read_reg() uses a stack-allocated char to get the read control value. This is wrong because usb_control_msg() requires a kmalloc-ed buffer. This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive the read value. While here, let's remove the urb_buf array which was meant for a similar purpose, but never really used.
