oh, I'm roughly on msm-next, so didn't see the revert.. I'll drop this
one. But with things in flux, this is why I decided against adding it
to DRM_GEM_FOPS. Ie. we should do that as a followup cleanup step
once everyone is moved over to the new helpers to avoid conflicts or
build breaks when merging things via different driver trees
