Currently, the Kbuild core manipulates header search paths in a crazy
way [1].

To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.

Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

Pull drm updates from Dave Airlie:
 "This has two exciting community drivers for ARM Mali accelerators.
  Since ARM has never been open source friendly on the GPU side of the
  house, the community has had to create open source drivers for the
  Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
  series. Well done to all involved and hopefully this will help ARM
  head in the right direction.

  There is also now the ability if you don't have any of the legacy
  drivers enabled (pre-KMS) to remove all the pre-KMS support code from
  the core drm, this saves 10% or so in codesize on my machine.

  i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
  moves out of staging.

  There are also some rcar-du patches which crossover with media tree
  but all should be acked by Mauro.

In vpbe_enum_outputs() we check if (temp_index >= cfg->num_outputs) but
the problem is that "temp_index" can be negative.  This patch changes
the types to unsigned to address this array underflow bug.

Depending on which video standard is used the driver needs to setup the
hardware to correctly handle fields. If stream is identified as NTSC
or PAL setup field detection and propagate the field detection signal.

Later versions of the datasheet have been updated to make it clear
that FLD register should be set to 0 when dealing with non-interlaced
field formats.

Restart the CSI-2 link if the CSI-2 receiver detects an error during
reception. The driver did nothing when a link error happened and the
data flow simply stopped without the user knowing why.

Change the driver to try and recover from errors by restarting the link
and informing the user that something is not right. For obvious reasons
it's not possible to recover from all errors (video source disconnected
for example) but in such cases the user is at least informed of the
error and the same behavior of the stopped data flow is retained.

The "b->index" is a u32 the comes from the user in the ioctl.  It hasn't
been checked.  We aren't supposed to use it but we're instead supposed
to use the value that gets written to it when we call videobuf_dqbuf().

The videobuf_dqbuf() first memsets it to zero and then re-initializes it
inside the videobuf_status() function.  It's this final value which we
want.

Hans Verkuil pointed out that we need to check the return from
videobuf_dqbuf().  I ended up doing a little cleanup related to that as
well.
