I guess this comment was more about the whole, not just patch 2/2, but
Daniel merged 1/2 already. IIUC you would have wanted to keep set_speed
there, but shall we just leave that to when we start using GMBUS on
SDVO? Patch 2/2 is pretty straightforward, but will also need some love
when enabling GMBUS.
Thoughts?
BR,
Jani.
