Subject: [PATCH net 0/4] mptcp: misc fixes for v6.19-rc8

Here are various unrelated fixes:

- Patch 1: when removing an MPTCP in-kernel PM endpoint, always mark the
  corresponding ID as "available". Syzbot found a corner case where it
  is not marked as such. A fix for up to v5.10.

- Patch 2: Linked to the previous patch, the variable name was confusing
  and was probably partly responsible for the issue fixed by patch 1. No
  "Fixes" tag: no need to backport that for the moment, but better to
  avoid confusion now.

- Patch 3: fix all existing kdoc warnings linked to MPTCP code. No
  "Fixes" tag: they were there for a while, and not considered as
  important to backport.

- Patch 4: silence a compiler (false-positive) warning in the selftests.
  No "Fixes" tag: it is a false-positive warning, only seen with some
  versions.
