This looks good to me, though I have one minor concern about the macro
name. (But if it's okay with the DRM folks, which it seems to be, I
won't object.)
Either way,

My only slight concern here is that it might be a little bit confusing
that a macro called DRM_RECT_INIT() accepts x/y/w/h, whereas the
actual struct drm_rect is x1/y1/x2/y2. If the macro were called
something like DRM_RECT_INIT_FROM_XYWH() or similar.
