Hi all,

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

  drivers/gpu/drm/i915/i915_reg.h

between commit:

  77cdd054dd2c ("drm/i915/pmu: Connect engine busyness stats from GuC to pmu")

from Linus' tree and commit:

  202b1f4c1234 ("drm/i915/gt: Move engine registers to their own header")

from the drm-intel tree.

I fixed it up (see below - maybe should be done better?) 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.

Stephen Rothwell
