Summary
irqchip/gic-v2m: Prevent use after free of gicv2m_get_fwnode()
Details

In the Linux kernel, the following vulnerability has been resolved:

irqchip/gic-v2m: Prevent use after free of gicv2mgetfwnode()

With ACPI in place, gicv2mgetfwnode() is registered with the pci subsystem as pcimsigetfwnodecb(), which may get invoked at runtime during a PCI host bridge probe. But, the call back is wrongly marked as __init, causing it to be freed, while being registered with the PCI subsystem and could trigger:

Unable to handle kernel paging request at virtual address ffff8000816c0400 gicv2mgetfwnode+0x0/0x58 (P) pcisetbusmsidomain+0x74/0x88 pciregisterhost_bridge+0x194/0x548

This is easily reproducible on a Juno board with ACPI boot.

Retain the function for later use.
