If it bothers you, send a patch, otherwise wait for it to bother someone
else enough to send a patch. ;)

But please avoid the overuse of all caps for regular words, or
capitalization except at the beginning of sentences. I'd go with
something like this all over the place:

"Link training failed, link rate %d, lane count %d\n"

But it hasn't bothered me enough to send a patch. ;)
