====================
net: mctp: struct sock lifetime fixes

This series is a set of fixes for the sock lifetime handling in the
AF_MCTP code, fixing a uaf reported by Noam Rathaus
<noamr@ssd-disclosure.com>.

The Fixes: tags indicate the original patches affected, but some
tweaking to backport to those commits may be needed; I have a separate
branch with backports to 5.15 if that helps with stable trees.

Of course, any comments/queries most welcome.
