[PATCH] of/irq: init struct resource to 0 in of_irq_to_resource()

[Sebastian Andrzej Siewior]

It almost does not matter because most users use only the ->start member
of the struct. However if this struct is passed to a platform device
which is then added via platform_device_add() then the ->parent member is
also used.
