Peter reported that /proc/bus/pci/??/??.? does not works for 3.6.
This is This is because the device configuration space registers will
be not accessible if the corresponding parent bridge is suspended or
the device is put into D3cold state.

This is the same as /sys/bus/pci/devices/0000:??:??.?/config access
issue.  So the function used to solve sysfs issue is used to solve
this issue.

Is this bug the same as the one originally reported by Forrest Loomis
(original reporter of bug 48981)?  And
https://bugzilla.kernel.org/show_bug.cgi?id=49031, reported by Micael
Dias (Rafael marked 49031 as a duplicate of 48981)?

If so, I'll mention Forrest and Micael and bug 49031 here as well.

No, it's not.  That one turned out to be a duplicate of bko#48981.

I applied this to my for-linus branch as v3.7 material.  Thanks!
