From: Yijing Wang Date: Mon, 27 Oct 2014 07:48:46 +0000 (+0800) Subject: ARM/PCI: Remove unused pcibios_add_bus() and pcibios_remove_bus() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6cf00af0ae158120e8149ed3d77746397b3f911f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ARM/PCI: Remove unused pcibios_add_bus() and pcibios_remove_bus() There are no users of the struct hw_pci.add_bus() or .remove_bus() methods, so remove the pointers from hw_pci. That makes pcibios_add_bus() and pcibios_remove_bus() themselves superfluous, so remove them as well.
