Right... ...and of_device_get_match_data() is declared in...
<linux/of.h>. :-) See commit 82174a0a9c5c ("of: Move
of_device_get_match_data() declaration") and commit 722d4f06e560
("drm: Explicitly include correct DT includes").

We'll probably need to handle that when picking to downstream, but for
upstream you shouldn't be re-introducing of_device.h.
