Subject: [PATCH] PCI: export symbol pci_bus_sem to module
Date: Mon, 28 May 2012 15:33:00 +0800	[thread overview]
Message-ID: <1338190380-5144-1-git-send-email-jiang.liu@huawei.com> (raw)

Changeset "9080648 PCI: acpiphp: remove all functions in slot,
even without ACPI _EJx" introduces pci_bus_sem into the acpiphp
driver, but pci_bus_sem hasn't been exported to modules yet.
So export symbol pci_bus_sem to modules, otherwise the acpiphp
driver can't be built as module any more.
