Bug Description

[SRU Justification]

[Impact]

Missed Modem Logging support.

[Fix]

Two upstream commits currently in linux-next for maybe v6.2.

[Test Case]

With corresponding libmbim fix in
https://gitlab.freedesktop.org/mobile-broadband/libmbim/-/merge_requests/161,

  $ mbimcli -d <dev-path> query-trace-config

[Where problems could occur]

This adds an logging channel that is only compiled when WWAN_DEBUGFS is
on, and takes a specific command to enable logging. Should be no harm in
general, and might have side-effects when turned on.

[Other Info]

This is not yet available in mainline kernel but in linux-next, so
Unstable, Lunar and OEM-6.0 are all nominated for fix.

This bug is awaiting verification that the linux-oem-6.1/6.1.0-1004.4 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
