Bug Description

== SRU Justification ==
The CONFIG_WWAN config is set to 'Y' for the generic and most derivative kernels. This is affecting custom driver development for some partners.

Change this config to be a loadable module and include it in linux-modules-*.

Make this change to -generic kernels, so all derivatives will inherit it.

== Fix ==
UBUNTU: [Packaging] Make WWAN driver loadable modules

== Regression Potential ==
Medium. This change is only to WWAN, and is changing it to a loadable module and not removing it.

== Test Case ==
A test kernel was built with this patch and tested by a partner. It was also compile and boot tested internally. Testing will also be performed on a WWAN device.

While preparing mantic I noticed that the change did not take into account the previous value.
CONFIG_WWAN policy<{'amd64': 'y', 'arm64': 'y', 'armhf': 'y', 'ppc64el': 'y', 'riscv64': 'm', 's390x': 'n'}>

I adapted the change for amd64 and arm64, but I am not sure if the rest of the arches are as expected, hence this comment.

Current config:
CONFIG_WWAN policy<{'amd64': 'm', 'arm64': 'm', 'armhf': 'y', 'ppc64el': 'y', 'riscv64': 'm', 's390x': 'n'}>

This bug is awaiting verification that the linux/5.15.0-90.100 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' to 'verification-done-jammy-linux'. If the problem still exists, change the tag 'verification-needed-jammy-linux' to 'verification-failed-jammy-linux'.

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!
