Sure I could, but I broke that long line intentionaly. Line lenght rule is
normally broken for string just to allow people grepping for error message in
source files and I guess everyone sane would grep for "Can't get PHY device for
port" which is on single line. So this way we:
1) respect 80 chars limit
2) have error message grepable.

Do you still insist on making this one long line? (I have no problem sending
v4, just wanted to give some rationale before I eventually do so)
