Subject: linux-next: manual merge of the drm-misc tree with the drm tree

Hi all,

Today's linux-next merge of the drm-misc tree got a conflict in
drivers/gpu/drm/drm_edid.c between commit 18df89fef2d5 ("drm: Decouple
EDID parsing from I2C adapter") from the drm tree and commit
d6885d659037 ("drm/edid: move drm_edid_is_zero to top, make edid
argument const") from the drm-misc tree.

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

Cheers,
