3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Ulbricht <michael.ulbri...@systec-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.
