As I said when you posted previously that's a problem anyway and
close_delayed_work() needs to be fixed. You had a half-posted patch,
did you manage to test it properly (even in normal operation)? I'd been

This is completely unrelated to driver code, the core's data is much
more of a problem than the register cache which will generally fix
itself the next time DAPM does anything.
