Hi Wolfram,

I see you didn't pick up the follow-up patch ("gpio: pca953x: add a
comment explaining the need for a lockdep subclass"). Linus acked it
in the end and I'd really prefer for it to go into 4.9, as I don't
know if I'll have time to complete the solution for the lockdep issue
in the next development cycle. Without this explanation, the random
lockdep_set_subclass() call looks out of place.

Thanks,
Bartosz
