Subject[031/123] USB: cdc-acm: Adding second ACM channel support for various Nokia and one Samsung phones
From: Toby Gray <toby.gray@realvnc.com>

commit 4035e45632c2a8bb4edae83c20447051bd9a9604 upstream.

S60 phones from Nokia and Samsung expose two ACM channels. The first is a modem
with a standard AT-command interface, which is picked up correctly by CDC-ACM.

The second ACM port is marked as having a vendor-specific protocol. This means
that the ACM driver will not claim the second channel by default.

This adds support for the second ACM channel for the following devices:
Nokia E63
Nokia E75
Nokia 6760 Slide
Nokia E52
Nokia E55
Nokia E72
Nokia X6
Nokia N97 Mini
Nokia 5800 Xpressmusic
Nokia E90
Samsung GTi8510 (INNOV8)
