[PATCH 5.15.y 0/6] Old missing backports

["Matthieu Baerts (NGI0)" <matttbe@kernel.org>]

When working on an issue in the MPTCP selftests due to a recent
backport, I noticed it was due to a missing backports. A few years ago,
we were not properly monitoring the failed backports, and we missed a
few patches:

- 857898eb4b28 ("selftests: mptcp: add missing join check")
- 0c1f78a49af7 ("mptcp: fix error mibs accounting")
- 31bf11de146c ("mptcp: introduce MAPPING_BAD_CSUM")
- fd37c2ecb21f ("selftests: mptcp: Initialize variables to quiet gcc 12 warnings")
- c886d70286bf ("mptcp: do not queue data on closed subflows")

An extra patch has been added to ease the other backports:

- b8e0def397d7 ("mptcp: drop unused sk in mptcp_push_release")

Geliang Tang (1):
  mptcp: drop unused sk in mptcp_push_release
