If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit cb764f6db097d0db53b7a8927350d9b60c62a13d Author: Daniele Palmas <dnlplm@xxxxxxxxx> Date: Mon Apr 10 17:34:23 2017 +0200 drivers: net: usb: qmi_wwan: add QMI_QUIRK_SET_DTR for Telit PID 0x1201 [ Upstream commit 14cf4a771b3098e431d2677e3533bdd962e478d8 ] Telit LE920A4 uses the same pid 0x1201 of LE920, but modem implementation is different, since it requires DTR to be set for answering to qmi messages. This patch replaces QMI_FIXED_INTF with QMI_QUIRK_SET_DTR: tests on LE920 have been performed in order to verify backward compatibility.
