This just renames this as we want to add an shm handle which isn't really drm related. Originally by: Marc-André Lureau <marcandre.lureau@gmail.com> (airlied: I used this sed script instead) This was generated with: git grep -l 'DRM_API_' | xargs sed -i 's/DRM_API_/WINSYS_/g' Reviewed-by: Marek Olšák <marek.olsak@amd.com>
