Sylwester Nawrocki 49b2f4c56f [media] exynos4-is: Remove support for non-dt platforms
All platforms supported by this driver are going to get device tree
support in this kernel release so remove code that would have been
actually not used any more.

Hans Verkuil e37559b22c [media] vb2: stop_streaming should return void
The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.

The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.

The pwc amd sdr-msi3101 drivers both had this construction:

        if (mutex_lock_interruptible(&s->v4l2_lock))
                return -ERESTARTSYS;

This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

Hans Verkuil 5f26f2501b [media] v4l2-pci-skeleton.c: fix alternate field handling
For interlaced HDTV timings the correct field setting is FIELD_ALTERNATE,
not INTERLACED. Update this template driver accordingly:

- add check for the invalid combination of read() and FIELD_ALTERNATE.
- in the interrupt handler set v4l2_buffer field to alternating TOP and
  BOTTOM.

Hans Verkuil b8da9d3aaf [media] sn9c102: prepare for removal by moving it to staging
During the last media summit meeting it was decided to move this driver to
staging as the first step to removing it altogether.

Most webcams covered by this driver are now supported by gspca. Nobody has the
hardware to convert the remaining devices to gspca.

This driver needs a major overhaul to have it conform to the latest frameworks
and compliancy tests.

Without hardware, however, this is next to impossible. Given the fact that
this driver seems to be pretty much unused (it has been removed from Fedora
several versions ago and nobody complained about that), we decided to drop
this driver.

This patch moves it to staging. Some time in 2014 we will drop it completely.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Hans Verkuil 34a6b7d093 [media] v4l2-ctrls: add a filter function to v4l2_ctrl_add_handler
With a filter function you can control more precisely which controls
are added. This is useful in particular for radio device nodes for
combined TV/Radio cards where you want to show just the radio-specific
controls and not controls like brightness.
