[Xen-devel] [PATCH] qemu: Don't access /proc/bus/pci unless graphics pass-thru is enabled

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

A recent changeset introduced a bug whereby an initialization function
that reads /proc/bus/pci is called from graphics set-up functions
even if pass-through graphics are not enabled.  If qemu is run without
permission to this file, this causes qemu to fail during initialization.

This patch changes the initialization functions to only happen if graphics
pass-through are enabled.
