Hi Lee,
Today's linux-next merge of the mfd tree got a conflict in:
drivers/gpu/drm/i915/intel_display.h
between commit:
ac213c1b45f7 ("drm/i915/icl: introduce tc_port")
from the drm tree and commit:
9c229127aee2 ("drm/i915: hdmi: add CEC notifier to intel_hdmi")
from the mfd 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.
