[PATCH 00/10] ipmi: kcs_bmc: Miscellaneous cleanups

[Andrew Jeffery <andrew@codeconstruct.com.au>]

Hello,

A cleanup of the KCS subsystem was prompted after some concerns raised
by Jonathan on Konstantin's series implementing DSP0254[1] (the MCTP KCS
Transport Binding Specification):

[1]: https://www.dmtf.org/sites/default/files/standards/documents/DSP0254_1.0.0.pdf

The MCTP KCS patches are currently at v5:

https://lore.kernel.org/all/20231010122321.823-1-aladyshev22@gmail.com/

A v6 will be necessary to rework them in terms of the cleanup done here.
I've pushed a preview of that work here:

https://github.com/amboar/linux/compare/d2cc82b50335c8fcf83e1d8f396c8f8cf4333ac4...mctp-kcs

In addition to addressing some of the resource lifetime concerns I've
added kerneldoc for the subsystem in anticipation of Konstantin's series
moving the headers to include/linux/.

To get Konstantin's work merged I expect we'll have to either take these
KCS patches through netdev or the MCTP patches through the IPMI tree. We
should figure out which way we want to go, but netdev's not open right
now and so that's not a pressing concern.

Please review!

Thanks,

Andrew
