Subject: PCI: xilinx: Don't call pci_fixup_irqs() on Microblaze
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=2c51391d2559a825a10e0abfbfb0e247d9c344b3;p=deliverable%2Flinux.git

PCI: xilinx: Don't call pci_fixup_irqs() on Microblaze

The Xilinx AXI PCIe Host Bridge Soft IP driver was previously only
supported on ARM (in particular, on ARCH_ZYNC), and pci_fixup_irqs() is
available there.  But Microblaze will do IRQ fixup in pcibios_add_device(),
so pci_fixup_irqs() is not available on Microblaze.

Don't call pci_fixup_irqs() on Microblaze, so the driver can work on both
Zynq and Microblaze Architectures.

[bhelgaas: revise changelog to show similarity to bdb8a1844f31 ("PCI: iproc: Call pci_fixup_irqs() for ARM64 as well as ARM")]
