I still beg to differ. Even if it fails, dmesg will still contain the
message (provided you have it enabled). I really don't think we want
this to print to console on every boot.

If you're still testing your new batch of boards, you're not just a
simple user and you will have debugging enabled anyway. dev_info() will
be visible to anyone who's got a console running. Not sure how useful
that would be to my neighbor.
