Masahiro Yamada - May 13, 2019, 6:22 a.m.
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 split this kind of changes per-subsystem,
and all of them were merged, except the media subsystem.

I sent ping several times to the media subsystem
but I could not get response at all.
https://lkml.org/lkml/2019/4/11/1040

It is almost 4 months since the submission.
Meanwhile, I asked 0day bot to test this, and I did not
get any problem report.
I am going to apply this to kbuild tree
since this is a prerequisite for the Kbuild core change.
