I don't think there is any real issue here. The two irq_desc's being locked are
always different, so there is no deadlock. This recursive irq_set_irq_wake seems
to be a reasonably common pattern in GPIO drivers, and several of them contain
code to silence lockdep. I've sent a patch adding a copy of that to the sunxi
driver:

Please see if it works for you.
Yes, it does. The warning is gone with your patch applied on top of linux-next.
Thanks,
Guenter
