*sigh* finally have some time to go through these reviews
jfyi: I realized after looking over this patch that it's not actually needed -
I had been planning on using drm_dp_dump_link_address() for other things, but
ended up deciding to make the final plan to use something that dumps into a
format that's identical to the one we're using for dumping DOWN requests. IMHO
though, this patch does make things look nicer so I'll probably keep it.
Assuming I can still count your r-b as valid with a change to the commit
description?
