Pending header cleanups will reveal this file is using the init.h content implicitly with the following fail: arch/tile/kernel/usb.c:69:1: warning: data definition has no type or storage class [enabled by default] arch/tile/kernel/usb.c:69:1: error: type defaults to 'int' in declaration of 'arch_initcall' arch/tile/kernel/usb.c:69:1: warning: parameter names (without types) in function declaration [enabled by default] arch/tile/kernel/usb.c:62:19: warning: 'tilegx_usb_init' defined but not used Explicitly add init.h to get arch_initcall and avoid this.
