When the media device registration fails, don't call media_device_unregister
since the device was never actually registered.
When removing the module also call media_device_cleanup() to avoid a memory leak.

While there's a control to allow setting it at runtime, as the
control handler is per file handler, only the application setting
the m2m device can change it. As this is a custom control, it is
unlikely that existing apps would be able to set it.
Due to that, and due to the fact that v4l2-mem2mem serializes all
accesses to a m2m device, trying to setup two GStreamer
v4l2videoconvert instance at the same time will cause frame drops.
So, add an alternate way of setting its default via a modprobe parameter.

Despite vim2m is reporting that it supports RGB565BE and YUYV,
that's not true.
Right now, it just says that it supports both format, but it
doesn't actually support them.
Also, horizontal flip is not properly implemented. It sounds
that it was designed to do a pseudo-horizontal flip using 8
tiles. Yet, as it doesn't do format conversion, the result
is a mess.
I suspect that it was done this way in order to save CPU time,
at the time of OMAP2 days.
That's messy and doesn't really help if someone wants to
use vim2m to test a pipeline.
Worse than that, the unique RGB format it says it supports is
RGB565BE, with is not supported by Gstreamer. That prevents
practical usage of it, even for tests.
So, instead, properly implement fourcc format conversions,
adding a few more RGB formats:
- RGB and BGR with 24 bits
- RGB565LE (known as RGB16 at gstreamer)
Also allows using any of the 5 supported formats as either
capture or output.
Note: The YUYV conversion routines are based on the conversion code
written by Hans de Goede inside libv4lconvert (part of v4l-utils),
released under LGPGL 2.1 (GPL 2.0 compatible).
Tested all possible format combinations except for RGB565BE,
as Gstreamer currently doesn't support it.

The wrong size check was performed for output formats like NV24 which
set vfmt->buffers to 1, but vfmt->planes is 2. It was incorrectly
checking the payload size for plane 1, which doesn't exist.
Note: vfmt->buffers refers to the number of per-plane-buffers that
should be allocated. vfmt->planes refers to the number of planes
that make up an image. vfmt->planes may be > vfmt->buffers.

Having of_reserved_mem_device_init() forcibly reconfigure DMA for all
callers, potentially overriding the work done by a bus-specific
.dma_configure method earlier, is at best a bad idea and at worst
actively harmful. If drivers really need virtual devices to own
dma-coherent memory, they should explicitly configure those devices
based on the appropriate firmware node as they create them.
It looks like the only driver not passing in a proper OF platform device
is s5p-mfc, so move the rogue of_dma_configure() call into that driver
where it logically belongs.

There is a block of code in rvin_group_link_notify() that prevents
enabling a link to a VIN node if any entity in the media graph is
in use. This prevents enabling a VIN link even if there is an in-use
entity somewhere in the graph that is independent of the link's
pipeline.
For example, the code block will prevent enabling a link from
the first rcar-csi2 receiver to a VIN node even if there is an
enabled link somewhere far upstream on the second independent
rcar-csi2 receiver pipeline.
If this code block is meant to prevent modifying a link if any entity
in the graph is actively involved in streaming (because modifying
the CHSEL register fields can disrupt any/all running streams), then
the entities stream counts should be checked rather than the use counts.
(There is already such a check in __media_entity_setup_link() that verifies
the stream_count of the link's source and sink entities are both zero,
but that is insufficient, since there should be no running streams in
the entire graph).
Modify the code block to check the entity stream_count instead of the
use_count (and elaborate on the comment). VIN node links can now be
enabled even if there are other independent in-use entities that are
not streaming.
