Date: Mon, 23 Nov 2015 14:09:04 +0100 From: Jiri Slaby <jslaby@...e.cz> To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Bjørn Mork <bjorn@...k.no>, "David S . Miller" <davem@...emloft.net>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 42/72] qmi_wwan: fix entry for HP lt4112 LTE/HSPA+ Gobi 4G Module From: Bjørn Mork <bjorn@...k.no> 3.12-stable review patch. If anyone has any objections, please let me know. =============== [ Upstream commit 70910791731b5956171e1bfcad707766b8e18fee ] 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.
