The kbuild modules.rst documentation says: The order of files in $(obj-y) is significant. Duplicates in the lists are allowed: the first instance will be linked into built-in.a and succeeding instances will be ignored. so you should be fine... or the documentation is wrong! -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
