Remove this function. This makes all vb2 queues behave the same, which

As usual, this patch is very large due to the fact that half a vb2 conversion
isn't possible. And since this affects blackbird, alsa, core, dvb, vbi and
video the changes are all over.
What made this more difficult was the peculiar way the risc program was setup.
The driver allowed for running out of buffers in which case the DMA would stop
and restart when the next buffer was queued. There was also a complicated
timeout system for when buffers weren't filled. This was replaced by a much
simpler scheme where there is always one buffer around and the DMA will just
cycle that buffer until a new buffer is queued. In that case the previous
buffer will be chained to the new buffer. An interrupt is generated at the
start of the new buffer telling the driver that the previous buffer can be
passed on to userspace.
Much simpler and more robust.

This patches fixes an ancient bug in the dvb_usb_af9005 driver, which
has been reported at least in the following threads:
https://lkml.org/lkml/2009/2/4/350
https://lkml.org/lkml/2014/9/18/558
If the driver is compiled in without any IR support (neither
DVB_USB_AF9005_REMOTE nor custom symbols), the symbol_request calls in
af9005_usb_module_init() return pointers != NULL although the IR
symbols are not available.
This leads to the following oops:

The prefered fix would be to convert the whole IR code to use the kernel IR
infrastructure (which wasn't available at the time this driver had been created).
Until anyone who still has this old hardware steps up an does the conversion,
fix it by not calling the symbol_request calls if the driver is compiled in
without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE).
Due to the IR related pointers beeing NULL by default, IR support will then be disabled.
The downside of this solution is, that it will no longer be possible to
compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in.
Please note that this patch has NOT been tested with all possible cases.
I don't have the hardware and could only verify that it fixes the reported
bug.

This patch partially reverts 0fb220f2a5cb. What happened is
that the conversion of debug messages to use pr_debug() was a
bad idea, because one needing to debug would need to both
enable debug level via a modprobe parameter, and then to
enable the dynamic printk's.
So, for now, let's use printk() directly at dprintk().

The warning is simple:
drivers/media/v4l2-core/v4l2-ctrls.c:1685:15: warning: incorrect type in assignment (different address spaces)
but the fix isn't.
The core problem was that the conversion from user to kernelspace was
done at too low a level and that needed to be moved up. That made it possible
to drop pointers to v4l2_ext_control from set_ctrl and validate_new and
clean up this sparse warning because those functions now always operate
on kernelspace pointers.
