Hi all,

Today's linux-next merge of the drm-intel tree got a conflict in:

drivers/gpu/drm/i915/i915_mm.c

between commit:

293837b9ac8d ("Revert "i915: fix remap_io_sg to verify the pgprot"")

from Linus' tree and commit:

ec279384c6a0 ("drm/i915: Initialize err in remap_io_sg()")

from the drm-intel 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.
