[Xen-devel] [PATCH v1 03/21] MSI: Remove the redundant irq_set_chip_data()

Currently, pcie-designware, pcie-rcar, pci-tegra drivers
use irq chip_data to save the msi_chip pointer. They
already call irq_set_chip_data() in their own MSI irq map
functions. So irq_set_chip_data() in arch_setup_msi_irq()
is useless.
