linux-next: manual merge of the drm-intel tree with Linus' tree

[sfr at canb.auug.org.au (Stephen Rothwell)]

Hi all,

Today's linux-next merge of the drm-intel tree got a conflict in
drivers/gpu/drm/i915/intel_panel.c between commit b1289371fcd5 ("Revert
"drm/i915: write backlight harder"") from Linus' tree and commit
31ad8ec6a614 ("drm/i915: group backlight related stuff into a struct")
from the drm-intel tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
