To my knowledge
https://lore.kernel.org/linux-bluetooth/9ca502845fc793f3f76c02aef316a273d3b6929c.1762026583.git.pav@iki.fi/T/#u
should fix the issue.

It's RFC patch though, I'm waiting for feedback from you as I don't
have a reproducer for the issue, and Luiz if we want to go this heavy
on lockdep / sparse.
