Subject: [PATCH 24/24] PCI: clean up rescan_bus_bridge_resize
Date: Sat, 4 Feb 2012 22:58:08 -0800 [thread overview]
Message-ID: <1328425088-6562-25-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1328425088-6562-1-git-send-email-yinghai@kernel.org>
Should only use it with bridge instead of bus.
it could get new subordinate. so can not use it with reguar bus.
in that case, use may need to make all children devices get removed already.
