Remark update_res from __init to __devinit as it is called also from __devinit functions. This patch removes the following warning message: WARNING: vmlinux.o(.devinit.text+0x774a): Section mismatch in reference from the function pci_root_bus_res() to the function .init.text:update_res() The function __devinit pci_root_bus_res() references a function __init update_res(). If update_res is only used by pci_root_bus_res then annotate update_res with a matching annotation.
