[Bug 2067240] Re: [SRU] Add Quectel EM061K-GL/EM160/RM520N PID information to support WWAN LVFS

Hi Atlas,

Thanks for looking into this.

Please merge all your changelog entries into a single one. Also, could
you please add some DEP-3 for the new patches added to the package? It
makes it easier to track down the context for a given patch.

I'm a bit foggy on the upgrade paths that are still possible for Jammy,
but in general when posting a SRU for 22.04, you should either fix it on
all subsequent releases that are still supported or justify why we
shouldn't, including interim releases. The rationale for this is that we
don't want regressions for users upgrading.

Title:
  [SRU] Add Quectel EM061K-GL/EM160/RM520N PID information to support
  WWAN LVFS

Status in OEM Priority Project:
  Confirmed
Status in modemmanager package in Ubuntu:
  New
Status in modemmanager source package in Jammy:
  New

Bug description:
  [ 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.
