USB: serial: option: set driver_info for SIM5218 and compatibles

mansr · jhovold · commit f8df5c2c3e2d · 2019-03-19T11:32:06.000+01:00
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.
