[Intel-gfx] linux-next: manual merge of the drm-misc tree with the tree

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the drm-misc tree got a conflict in
drivers/gpu/drm/drm_edid.c between commit 40d9b043a89e ("drm/connector:
store tile information from displayid (v3)") from the drm tree and
commit d6885d659037 ("drm/edid: move drm_edid_is_zero to top, make edid
argument const") and c465bbc87ce3 ("drm/edid: new
drm_edid_block_checksum helper function V3") from the drm-misc tree.

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