USB: serial: option: update interface mapping for ZTE P685M 2021-03-03T16:44:41+00:00 Lech Perczak lech.perczak@gmail.com 2021-02-07T00:54:43+00:00 2ed4d2a139ab7fc93ec5407aaecebcec3b180da9 commit 6420a569504e212d618d4a4736e2c59ed80a8478 upstream. This patch prepares for qmi_wwan driver support for the device. Previously "option" driver mapped itself to interfaces 0 and 3 (matching ff/ff/ff), while interface 3 is in fact a QMI port. Interfaces 1 and 2 (matching ff/00/00) expose AT commands, and weren't supported previously at all. Without this patch, a possible conflict would exist if device ID was added to qmi_wwan driver for interface 3. Update and simplify device ID to match interfaces 0-2 directly, to expose QCDM (0), PCUI (1), and modem (2) ports and avoid conflict with QMI (3), and ADB (4). The modem is used inside ZTE MF283+ router and carriers identify it as such.

The modem is used inside ZTE MF283+ router and carriers identify it as
