commit f38ba5459ced3441852f37f20fcfb7bd39d20f62 upstream. Currently, irqchips for all of the subnodes (which represent a given bus master) point to the parent wrapper node. This is no bueno, as no interrupts arrive, ever (because nothing references that node). Fix that by passing a reference to the respective master's of_node. Worth noting, this is a NOP for devices with only a single master described.
