The irq_set_wake() function of the gpio irq_chip calls enable/disable_irq_wake() on the demultiplex interrupt. That leads to a lockdep warning "INFO: possible recursive locking detected" because irq_set_type() is called under irq_desc->lock and the *_irq_wake() calls take irq_desc->lock of the demux interrupt. Tell lockdep that the gpio irqs are in a different lock class. Documentation/SubmitChecklist: 15: All codepaths have been exercised with all lockdep features enabled. That's a non-optional requirement, AFAICT.
