From: Tim Kientzle <kient...@freebsd.org>
The patch below fixes device enumeration through the U-Boot API.
Device enumeration crashes when the system in question doesn't
have any RAM mapped to address zero (I discovered this on a
BeagleBone board), since the enumeration calls get_dev with a
NULL ifname sometimes which then gets passed down to strncmp().
This fix simply ensures that get_dev returns NULL when invoked
with a NULL ifname.

- resend with fixed whitespace errors and properly added
commit log.
I've queued this patch in my staging branch. Thanks!
