From: Tim Kientzle kientzle@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.

I've queued this patch in my staging branch. Thanks!
