[PATCH] USB: serial: option: add HP lt4132

From: Tore Anderson
Date: Sat Dec 08 2018 - 13:23:45 EST


The HP lt4132 is a rebranded Huawei ME906s-158 LTE modem.

The interface with protocol 0x16 is "CDC ECM & NCM" according to the *.inf
files included with the Windows driver. Attaching the option driver to it
doesn't result in a /dev/ttyUSB* device being created, so I've excluded it.
Note that it is also excluded for corresponding Huawei-branded devices, cf.
commit d544db293a44a.
