Right. So looks like I am still the guilty one then. I've overwritten
the fix in this rename patch which followed the corrected initial
support patch. I guess sending incremental patch with fix to regulator
tree is correct way to go, right? I'll prepare one against Mark's branch
"origin/topic/bd718xx". Mark, please let me know if you want me to send
it or if I should do it on top of some other branch.
