Subject: [PATCH 09/10] arm/PCI: Clean unused pcibios_add_bus() and pcibios_remove_bus()
Date: Mon, 27 Oct 2014 15:48:46 +0800 [thread overview]
Message-ID: <1414396127-30023-10-git-send-email-wangyijing@huawei.com> (raw)
In-Reply-To: <1414396127-30023-1-git-send-email-wangyijing@huawei.com>
MSI controller has been saved in pci_sys_data, now we can
clean up pcibios_add_bus() and pcibios_remove_bus()
in arm, and use pcibios_msi_controller() to get MSI controller
pointer.
