To reproduce the conflict and resubmit, you may use the following commands:
git fetch https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/ linux-5.4.y
git checkout FETCH_HEAD
git cherry-pick -x a6f88ac32c6e63e69c595bfae220d8641704c9b7

These 3 commits are the actual dependencies:
[1] 61cc4534b655 ("locking/lockdep: Avoid potential access of invalid memory in lock_class")
[2] 248efb2158f1 ("locking/lockdep: Rework lockdep_lock")
[3] 10476e630422 ("locking/lockdep: Fix bad recursion pattern")
It seems to me that [1] and [3] are fixes we would also want in 5.4.
Possibly also [2] just to make the cherry-picks cleaner. If there are no
objections I can send a patchset for linux-5.4.y with all 4?
SGTM!
