If anyone has any objections, please let me know. ------------------ From: =?UTF-8?q?Bj=C3=B8rn=20Mork?= commit 749541d19e70905e3971f2a08335a206a98e4d0c upstream. These devices have a number of non serial interfaces as well. Use the existing "Direct IP" blacklist to prevent binding to interfaces which are handled by other drivers. We also extend the "Direct IP" blacklist with with interfaces only seen in "QMI" mode, assuming that these devices use the same interface numbers for serial interfaces both in "Direct IP" and in "QMI" mode.
