3.16.7-ckt21 -stable review patch. If anyone has any objections, please let me know.
------------------ From: =?UTF-8?q?Bj=C3=B8rn=20Mork?= <[email protected]> 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.
