sparse complains about linux/types.h not being included, so I wonder if
it makes more sense to include that instead of drm/drm.h. In fact I have
a fix that does exactly that in a local branch and was going to put that
into my fixes branch. It's a bit more lightweight.

On the other hand, some drivers already include drm/drm.h in the public
header so I don't really have any objections to this patch.

Hi Thierry,

I don't know this code well but the drm/drm.h has an #if def so that
either linux/types.h is included or the __[us]* types are defined in
a different way with the comment "One of the BSDs".
Also I sent a patch last year to include linux/types.h in exynos_drm.h
but it now includes drm/drm.h instead.

Best regards,

Emil Goode
