4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Grygorii Strashko <[email protected]> commit 63059a272398ef5dc1bd7065a036e8b6e82d1af7 upstream. The conversion of the wakeupgen irqchip to hierarchical irq domains failed to provide a mechanism to properly set the trigger type of an interrupt. The wakeupgen irq chip itself has no mechanism and therefor no irq_set_type() callback. The code before the conversion relayed the trigger configuration directly to the underlying GIC. Restore the correct behaviour by setting the wakeupgen irq_set_type callback to irq_chip_set_type_parent(). This propagates the set_trigger() call to the underlying GIC irqchip.
