commit e7e0c3e26587749b62d17b9dd0532874186c77f7 upstream. The number of planes in videobuf2 is specific to a buffer. In order to verify that the planes array provided by the user is long enough, a new vb2_buf_op is required. Call __verify_planes_array() when the dequeued buffer is known. Return an error to the caller if there was one, otherwise remove the buffer from the done list.
