Public bug reported: [ Impact ]
The modemmanager v1.20.0 doesn't have Quectel EM061K-GL/EM160/RM520N PID information, and the modemmanger won't recognize these WWAN modems on some next-gen Lenovo laptops. (lp: #2045276) [ Test Plan ] Under Jammy environment, with latest linux-oem kernel installed, check output of `mmcli -L` to see if the modems are properly recognized. Modems to check: - EM061K-GL - EM160 - EM160 [ Where problems could occur ] EM160R-GL(1.22.0): https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1059/diffs EM061K-GL(1.22.0): https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1057/diffs RM520N-GL(1.22.0): https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1052/diffs https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1077/diffs All these changes are merged, and they only introduce new PIDs for initial supports, which do not affect existing ones. Noble contains these changes, so, only SRU jammy.
