And thanks for the review! :)

Yeah, I wondered about this... did not think it mattered too much
because it just ships some patch files used as an input; it is not a
package someone is likely to include in a profile where the version
would matter. Might be a case for using (define ... instead of
(define-public ... of course I can make up a more meaningful
git-commit-hash derived version if we absolutely must... :)

Current head is probably also fine (seems to have one new or updated
patch to the relevent kernel patches which might require adjusting patch
phase), but that was the commit I tested so far.

Sounds plausible to me. :)

FWIW, I am also fine with dropping anything outside of linux/ in a
snippet, if it makes the licensing simpler, as we really use none of
the other files.

Most .dts related files in linux are dual-licensed under GPL and one of
various permissive licenses ... (e.g. GPL-2* OR BSD|MIT|X11).

That's good to know. I am a little less familiar with GNU licensing
conventions, mostly coming from Debian, while not totally different,
have some different conventional takes.

Also useful, thanks!

I can probably get upstream to fix that, but we also do not need it at
all.

I focused on linux/patches6.12 mainly, as those were the ones I am
actually using, and other than the device-tree patches that are
dual-licensed, likely all the rest should be gpl2 or gpl2+.


live well,
