The second paragraph here seems redundant (and sounds like it might have
been the commit message for a second commit you squashed into the first
since the "This" is ambigous).
Also, there are still a bunch of remaining intel_dig_port
parameters/variables. Maybe we want an additional patch to drop the
intel_ prefix from those and make everything consistent? At this point
I think we've dropped the intel_ prefix from most/all of our crtcs,
planes, etc. so it probably makes sense to do the same here with
dig_ports.
