       - drivers should not assume umem SGLs are in PAGE_SIZE chunks
       - ucontext is accessed via udata not other means
       - start to make the core code responsible for object memory
         allocation
       - drivers should convert struct device to struct ib_device via a
         helper
       - drivers have more tools to avoid use after unregister problems"

earth-pt1 driver was decomposed/restructured by the commit b732539efdba
("media: dvb: earth-pt1: decompose pt1 driver into sub drivers"),
but it introduced a problem regarding concurrent streaming:
Opening a new terrestial stream stops the reception of an existing,
already-opened satellite stream.

The demod IC in earth-pt1 boards contains 2 pairs of terr. and sat. blocks,
supporting 4 concurrent demodulations, and the above problem was because
the config of a terr. block contained whole reset/init of the pair blocks,
thus each open() of a terrestrial frontend wrongly cleared the config of
its peer satellite block of the demod.
This whole/pair reset should be executed earlier and not on each open().

As we did lots of change at vim2m driver, let's take the
opportunity and make checkpatch happier, addressing the
errors/warnings that makes sense.

While here, increment driver's version.

No functional changes.

There's no reason why this driver should use BUG(). Instead,
just properly handle issue, returning an error code where
pertinent.

When in passthrough mode, copy the entire line at once, in

Add an horizontal linear scaler using Breseham algorithm in
order to speep up its calculus.

Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

Handling any Y,Cr,Cb formats require some extra logic, as it
handles a group of two pixels. That's easy while we don't do
horizontal scaling.

However, doing horizontal scaling with such formats would require
a lot more code, in order to avoid distortions, as, if it scales
to two non-consecutive points, the logic would need to read 4
points in order to properly convert to RGB.

As this is just a test driver, and we want fast algorithms,
let's just get rid of this format as an output one.
