Bug Description

[SRU Justification]

[Impact]

Missing usb serial interface for FM101R-GL.

[Fix]

* commit 52480e1f1a25 ("USB: serial: option: add Fibocom to DELL custom modem FM101R-GL"): in v6.6-rc7
* commit a1092619dd28 ("USB: serial: option: fix FM101R-GL defines"): in v6.7-rc3

[Test Case]

1. check lsusb & dmesg output
```
$ lsusb
Bus 004 Device 002: ID 413c:8215 Dell Computer Corp. Fibocom FM101-GL Module
...
$ sudo dmesg
[ 8.460678] usbcore: registered new interface driver usbserial_generic
[ 8.460690] usbserial: USB Serial support registered for generic
[ 8.549734] usbcore: registered new interface driver option
[ 8.550108] usbserial: USB Serial support registered for GSM modem (1-port)
[ 8.550266] option 4-4:1.2: GSM modem (1-port) converter detected
[ 8.553584] usb 4-4: GSM modem (1-port) converter now attached to ttyUSB0
[ 8.556445] usbcore: registered new interface driver cdc_ncm
[ 8.601187] usbcore: registered new interface driver cdc_wdm
[ 9.059744] cdc_mbim 4-4:1.0: setting rx_max = 16384
[ 9.060079] cdc_mbim 4-4:1.0: cdc-wdm0: USB WDM device
[ 9.060338] wwan wwan0: port wwan0mbim0 attached
```

2. make sure ModemManager has probed it:
```
$ mmcli -L
    /org/freedesktop/ModemManager1/Modem/0 [Fibocom Wireless Inc.] Fibocom FM101-GL Module
```

[Where problems could occur]

New hardware, still under development. Maybe we'll have to enable/patch for its vendor specific interface or so.

[Other Info]

The first patch is available for v6.6, and the second for v6.7. While we're enabling it on linux-oem-6.5/jammy, nominate for linux/noble, which is currently on v6.6, and linux-oem-6.5.

This bug is awaiting verification that the linux-oem-6.5/6.5.0-1010.11 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-linux-oem-6.5' to 'verification-done-jammy-linux-oem-6.5'. If the problem still exists, change the tag 'verification-needed-jammy-linux-oem-6.5' to 'verification-failed-jammy-linux-oem-6.5'.

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.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
