Userspace shouldn't set bytesused to 0 for output buffers.
vb2_warn_zero_bytesused() warns about this (only once!), but it also
calls WARN_ON(1), which is confusing since it is not immediately clear
that it warns about a 0 value for bytesused.
Just drop the WARN_ON as it serves no purpose.

Here's a new version of the Rockchip VPU JPEG encoder driver,
for the RK3288 and RK3399 SoCs.
This new version supports V4L2_PIX_FMT_JPEG capture format,

Trace points are much more efficient than debug messages for intensive

let's replace debug messages with the trace points. This also makes

Calling VIDIOC_DQBUF can release the core serialization lock pointed to
by vb2_queue->lock if it has to wait for a new buffer to arrive.
However, if userspace dup()ped the video device filehandle, then it is
possible to read or call DQBUF from two filehandles at the same time.
It is also possible
If queue->lock is different from the video_device lock, then
you need to serialize queue_setup with VIDIOC_S_FMT, and this

Hi Shuah, Mauro,
I noticed that the function vb2_core_streamon() in videobuf2-core.c calls
v4l_vb2q_enable_media_source(q).
That function in turn assumes that q->owner is a v4l2_fh struct. But I
don't think that is true for DVB devices.
And since videobuf2-core.c is expected to be DVB/V4L indepe
