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 a65851af5938 ("drm/i915:
Make data/link N value power of two") from Linus' tree and commit
e3b95f1eb5b9 ("drm/i915: Apply OCD to data/link m/n register #defines")
from the drm-intel tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
Daniel, I assume all this stuff being added to the drm-intel tree is
going upstream very soon?
