Only applying patches that may be necessary is absolutely non-trivial to compute, especially with dependent patchsets or future changes to the config.

I already provide monthly software updates for 170 devices using this tool which I've personally tested on two dozen devices plus many user reports on others. Making a (near) working PR conversation starter to demonstrate the tool I've spent years of my time on is my contribution.

In this case where I didn't have a PinePhone I explicitly found a closest match (Google Pixel 1/marlin iirc) to the kernel at hand and applied my fix database to it as matching to increase the chance that it would be successful.

I have absolutely zero doubts that someone can't apply the PR and be up and running in an hour.
