Above 4 members don't be used.
Oops yeah, I'll fix up the comments.

+struct drm_mode_get_plane {

I wonder why doesn't give to user crtc_x, crtc_y, crtc_w, crtc_h
information?
It could, but the caller should already know was my thinking. Would
you like those bits returned?
I saw such codes in initial your RFC patch version so i just have
wondered why it is removed. It can be added later if needs.
Thanks.
