v2: - remove USB controller registration, it will be added
      by a separate patch-set

Ralf,

The mach-db120.c file is licensed under the Clear BSD license. That
is based on the modified BSD license and the FSF's [1] site states
that it is compatible with both the GPLv2 and GPLv3.

However if you have concerns about the copyright we can resubmit
this file under the ISC license [2]. The ISC license is already
used upstream by the ath6kl and ath9k drivers.

Thanks,
Gabor
