Subject: [PATCH] i386: Only call unreachable_devices() when type 1 is available.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5f027387bbdb5a4a4c1babd557fd976cd09d7495;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] i386: Only call unreachable_devices() when type 1 is available.

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.
