   # HEAD: 38a05c0b87833f5b188ae43b428b1f792df2b384 irqchip/qcom-mpm: Prevent crash when trying to handle non-wake GPIOs

Two fixes:

 - Prevent NULL pointer dereference in msi_domain_debug_show()

 - Fix crash in the qcom-mpm irqchip driver when configuring
   interrupts for non-wake GPIOs

 Thanks,

	Ingo
