Subject: [PATCH v2] drm: prefix header search paths with $(srctree)/

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").

I put all gpu/drm changes into a single patch because
they are trivial conversion.

If you are interested in the big picture of this work,
the full patch set is available at the following URL.

git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git build-test


Changes in v2:
- fix up the new driver komeda
- Add Sam's Reviewed-by

For komeda:

Acked-by: Liviu Dudau <[email protected]>

I'm assuming the series in going to be merged into one go, so I don't
have to take the individual patch in my tree, but if I'm wrong please
let me know.

Best regards,
