Subject: [PATCH 2.6.21 review I] [15/25] i386: Only call unreachable_devices() when type 1 is available.


From: Olivier Galibert <galibert@...ox.com>

unreachable_devices compares between the results of pci configuration accesses
through type1 and mmconfig, so it should be called only if type1 actually
works in the first place.
