From cc74d96f47b0d916840f92092595e3be9731e047 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 12 Mar 2008 21:48:03 -0700 Subject: PCI: fix issue with busses registering multiple times in sysfs PCI busses can be registered multiple times, so we need to detect if we have registered our bus structure in sysfs already. If so, don't do it again. Thanks to Guennadi Liakhovetski for reporting the problem, and to Linus for poking me to get me to believe that it was a real problem.
