Subject: [PATCH 3.8 018/121] USB: cdc-acm: Remove Motorola/Telit H24 serial interfaces from ACM driver

3.8.13.24 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Michael Ulbricht <michael.ulbricht@...tec-electronic.com>

commit 895d240d1db0b2736d779200788e4c4aea28a0c6 upstream.

By specifying NO_UNION_NORMAL the ACM driver does only use the first two
USB interfaces (modem data & control). The AT Port, Diagnostic and NMEA
interfaces are left to the USB serial driver.
