Subject: [PATCH] USB: serial: option: Add support for Quectel EP06
Git-commit: 71a0483d56e784b1e11f38f10d7e22d265dbe244
Patch-mainline: v4.16-rc3
References: bsc#1051510

The Quectel EP06 is a Cat. 6 LTE modem, and the interface mapping is as
Follows: 

0: Diag
1: NMEA
2: AT
3: Modem

Interface 4 is QMI and interface 5 is ADB, so they are blacklisted.

This patch should also be considered for -stable. The QMI-patch for this
modem is already in the -stable-queue.

V1->v2: 
* Updated commit prefix (thanks Johan Hovold)
* Updated commit message slightly.
