Newer +Qualcomm chipset generations require setting DTR to wake the QMI +function. The SIM7600E modem is using such a chipset, making it +fail to work with this driver despite the device ID match. + +Fix by unconditionally enabling the SET_DTR quirk for all SIMCOM +modems using this specific device ID. This is similar to what +we already have done for another case of device IDs recycled over +multiple chipset generations: 14cf4a771b30 ("drivers: net: usb: +qmi_wwan: add QMI_QUIRK_SET_DTR for Telit PID 0x1201") + +Initial testing on an older SIM7100 modem shows no immediate side +effects. + +Reported-by: Sebastian Sjoholm <sebastian.sjoholm@gmail.com> +Cc: Reinhard Speyerer <rspmn@arcor.de> +Signed-off-by: Bjørn Mork <bjorn@mork.no> +Signed-off-by: David S.
