MCTP patches for dev-5.15 kernel

[Jeremy Kerr]

Hi Joel,

I figure it'd be handy to have the upstream MCTP support included in an
OpenBMC kernel, so have put together this backport tree:

https://github.com/CodeConstruct/linux/tree/backports/mctp/v5.15-openbmc

[this is just cherry-picked commits from upstream, applied to recent
dev-5.15. All commits have the upstream reference included in their
commit log]

Would you be willing to merge these for the 5.15 OpenBMC kernel?

Thanks!


Jeremy
