Hi Joe,
Thank you for the patch.
I think this would be easier to review if it were in 3 pieces:
1/3- add gem_objs to fb
2/3- driver conversion to gem_objs
3/3- remove create_handle()

Aside from Dave's comment about vmwgfx, I'm also getting link errors:
ERROR: "mtk_fb_get_gem_obj" [drivers/gpu/drm/mediatek/mediatek-drm.ko] undefined!
Consider using the drm-misc configs located here for your compile tests:
