Merge tag 'for-linus-6.1-1' of https://github.com/cminyard/linux-ipmi
Pull IPMI updates from Corey Minyard:
"Fix a bunch of little problems in IPMI
This is mostly just doc, config, and little tweaks. Nothing big, which
is why there was nothing for 6.0. There is one crash fix, but it's not
something that I think anyone is using yet"
