Hi Dave,
Today's linux-next merge of the drm tree got a conflict in
drivers/gpu/drm/i915/intel_display.c between commit 7aa1e7f06d6e ("Revert
"drm/i915: allow PCH PWM override on IVB"") from Linus' tree and commit
8090c6b9daa0 ("drm/i915: wrap up gt powersave enabling functions") from
the drm tree.
Just context changes (I think). I fixed it up (see below) and can carry
the fix as necessary.
