X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3aa8a41e0bf5565946082d23ae589c1a8559494a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

PCI: Add IRQ mapping function pointers to pci_host_bridge struct

In order to defer IRQ assignment arches must be able to register functions
to map and swizzle interrupts.  These registered functions are stored in
the pci_host_bridge struct.
