[ 01/21] USB: option: blacklist network interface on Huawei E1820

[Greg Kroah-Hartman]

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: BjÃrn Mork <bjorn@xxxxxxx>

commit b8a24e6281d37243c06b9497dcbfaa98c1e2ad35 upstream.

The mode used by Windows for the Huawei E1820 will use the
same ff/ff/ff class codes for both serial and network
functions.
