Hi all,
Today's linux-next merge of the drm-msm tree got a conflict in:
drivers/gpu/drm/msm/Makefile
between commit:
7c972986689b ("kbuild: use $(src) instead of $(srctree)/$(src) for source directory")
from the kbuild tree and commits:
0fddd045f88e ("drm/msm: generate headers on the fly")
07a2f8716c41 ("drm/msm/gen_header: allow skipping the validation")
from the drm-msm tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

This is now conflict between the drm tree and the kbuild tree.

And now a conflict between the kbuild tree and Linus' tree.
