Upcoming workqueue updates will no longer guarantee fixed workqueue to
worker kthread association, so giving RT priority to the irq worker
won't work. Use kthread_worker which guarantees specific kthread
association instead. This also makes setting the priority cleaner.

Hi,
As far as I understand it, the FE_SET_FRONTEND ioctl is supposed to tell a DVB
device to tune itself, and will send a poll() event when it completes. The
"frequency" parameter of this event will be the frequency of the newly tuned
channel, or 0 if tuning failed.

In my previous change to this driver, I was not aware, that dvb_usb_device_init
calls the frontend_attach routine which needs a transfer
buffer. So we can not setup anything private in the probe routine beforehand but
have to allocate when needed. This means also that we cannot use a private
buffer

To support multi-size buffers in the mx3_camera V4L2 driver we have to be
able to stop DMA on a channel without releasing descriptors and completely
halting the hardware. Use the DMA_PAUSE control to implement this mode.

Supporting new V4L2 ioctl()s in the mx3_camera driver also requires an
extension for the ipu-idmac dmaengine driver. The original thread, adding
the ioctl()s can be found here:

The fix is to check for ret and return -EFAULT if non-zero.

If there are no objections, then I'll make a pull request this weekend.

Hi Guennadi,
The mx2_camera driver is allocating one "discard" buffer of the same
size,
as regular buffers for cases, when the user is not fast enough to queue
new buffers for the running capture. Arguably, this could be aliminated
and the last submitted buffer could be re-used until either

This patch changes the order of operations during stream on call. Now the
buffers are first queued to the driver and then the start_streaming method

This resolves the most common case when the driver needs to know buffer
addresses to enable dma engine and start streaming. Additional par
