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.

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.
