Hi all,
Today's linux-next merge of the drm tree got a conflict in:
drivers/gpu/drm/i915/i915_reg.h
between commit:
54395a33718a ("drm/i915/dmc: Add MMIO range restrictions")
from the drm-intel-fixes tree and commit:
9c67d9e84c7d ("drm/i915/dmc: split out dmc registers to a separate file")
from the drm tree.
I fixed it up (I used the latter version of this file and applied the
following patch) 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.
