Subject: [PATCH part3 02/11] PCI: Move back pci_rescan_bus() to probe.c
Date: Sun,  2 Sep 2012 14:52:12 -0700	[thread overview]
Message-ID: <1346622741-30799-3-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1346622741-30799-1-git-send-email-yinghai@kernel.org>

We have pci_assign_unassigned_bus_resources() in as global function now.

So could move back pci_rescan_bus to probe.c where it should be.

Signed-off-by: Yinghai Lu <yinghai@kernel.org>
