I can't judge the semantic patch, but the C code change looks good to me.

Could you rebase this series over the latest drm-misc-next? The
recently merged patch "drm: Nuke drm_atomic_helper_connector_dpms"
causes conflicts with these.

drm-misc-next:

https://cgit.freedesktop.org/drm/drm-misc/log/

Thanks,
Archit

I got bored and fixed up the conflicts (wiggle pulled it off). All
applied, no need to resend.
