Looks good, except for readability I would add an empty line after "Such
as:".

I noticed that the signal patch depends on this patchset:

https://patchwork.kernel.org/project/linux-wireless/patch/20240219111417.1185-1-quic_lingbok@quicinc.com/

In that you should submit both patchses in same patchset. But please
wait until I have reviewed the signal strength patch.
