Subject: [PATCH 4.4 119/131] USB: serial: option: set driver_info for SIM5218 and compatibles

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

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

From: Mans Rullgard <mans@...sr.com>

commit f8df5c2c3e2df5ffaf9fb5503da93d477a8c7db4 upstream.

The SIMCom SIM5218 and compatible devices have 5 USB interfaces, only 4
of which are serial ports.  The fifth is a network interface supported
by the qmi-wwan driver.  Furthermore, the serial ports do not support
modem control signals.  Add driver_info flags to reflect this.
