modemmanager: Fix Quectel modems initialization bug

floion commented 3 months ago

With the update to ModemManager version 1.22.0 we now have some Quectel modems failing to use QMI properly:

ModemManager[1178]: [modem0] power state updated: on ModemManager[1178]: [modem0] (quectel) modem reset detected, triggering reprobe ModemManager[1178]: [modem0] (quectel) modem reset detected, triggering reprobe . . . ModemManager[1178]: [modem0] failed waiting for final state: Too much time waiting to get to a final state ModemManager[1178]: [modem0] failed enabling modem: Operation was cancelled ModemManager[1178]: [modem1] couldn't start initialization: Transaction timed out ModemManager[1178]: [modem1] fatal error initializing: Fatal error: modem is unusable

This has been fixed upstream with the 2 patches we backport here:

ModemManager[1139]: [modem0] power state updated: on ModemManager[1139]: [modem0] (quectel) continuing without enabling profile manager events
