I'm wondering if a good next step wouldn't be to require users to run it 
as well as checkpatch before submitting patches?

We can take our time to fix the current codebase but making sure none 
gets introduced is necessary otherwise we'll be chasing a clean codebase 
forever. And I think this could also catch sneaky merge order issues, 
e.g. someone adds support for a new board before/while the symbol is 
removed/renamed.

We should be able to enforce both checkpatch and checkkconfigsymbols.py 
to be run with b4 prep --check (and b4 am/shazam --check), see 
https://b4.docs.kernel.org/en/latest/config.html#term-b4.prep-perpatch-check-cmd 
and 
https://b4.docs.kernel.org/en/latest/config.html#term-b4.am-perpatch-check-cmd

However, I don't think this script is ready to be used with b4. As far 
as I understood it, b4 sends the patch to the tool's stdin, so we'd need 
to add support for such a thing.

Imported the script from v7.0-rc1, same as the one in this patch, thus:
