4.2.8-ckt1 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: =?UTF-8?q?Bj=C3=B8rn=20Mork?= <bj...@mork.no>
commit 70910791731b5956171e1bfcad707766b8e18fee upstream.
The lt4112 is a HP branded Huawei me906e modem. Like other Huawei
modems, it does not have a fixed interface to function mapping.
Instead it uses a Huawei specific scheme: functions are mapped by
subclass and protocol.
However, the HP vendor ID is used for modems from many different
manufacturers using different schemes, so we cannot apply a generic
vendor rule like we do for the Huawei vendor ID.
Replace the previous lt4112 entry pointing to an arbitrary interface
number with a device specific subclass + protocol match.
