This causes ipic_set_irq_type to set the handler directly rather than call set_irq_handler, which causes spinlock recursion because the lock is already held when ipic_set_irq_type is called. I'm also not convinced that ipic_set_irq_type should be changing the handler at all. There seem to be several controllers that don't and several that do. Those that do would break what appears to be a common usage of calling set_irq_chip_and_handler followed by set_irq_type, if a non-standard handler were to be used. OTOH, irq_create_of_mapping() doesn't set the handler, but only calls set_irq_type(). This patch gets things working in the spinlock-debugging-enabled case, but I'm curious as to where the handler setting is ideally supposed to be done. I don't see any documentation on set_irq_type() that clarifies what the semantics are supposed to be.
