Please don't send upstream things to my work address, it's unlikely to get read normally.

To repeat what I said off-list the lockdep splat looks like yet another case of lockdep generating false positives by being unable to work out that two different instances of objects of the same type are different objects.
Without more information on the system you're looking at, especially what regulators are involved and how they are related it's hard to tell what's going on as a result, getting some trace from the tracepoints would be more useful. Nothing obvious is jumping out from the code. [unhandled content-type:application/pgp-signature] | |
