infinite loop in PCI scan code on arm

[Philip Blundell <pb@nexus.co.uk>]

A couple of days ago, I mentioned to Branden on IRC that I was having a
problem with the PCI bus scan looping forever on some ARM systems with
the 4.3 prerelease code.  He suggested that I try this patch from the
HEAD:
http://cvsweb.xfree86.org/cvsweb/xc/programs/Xserver/hw/xfree86/common/xf86pciBus.c.diff?r1=3.68&r2=3.69&f=h

I've done a local rebuild with this change applied and it does indeed
seem to solve the problem.  If this could be included in the next
version of the Debian packages, I'd appreciate it.

Thanks
