Add stubs for some usb core functions when CONFIG_USB is not enabled. This fixes these comedi build errors:
ERROR: "usb_deregister" [drivers/staging/comedi/comedi.ko] undefined! ERROR: "usb_register_driver" [drivers/staging/comedi/comedi.ko] undefined!
Signed-off-by: Randy Dunlap<rdunlap@xxxxxxxxxxxx> --- I am only adding the stubs that are needed for comedi to build. I expect that more stubs will be needed as more build errors are found. It seems to me that linux/usb.h might need more (major) moving of lines to support more stubs in the future.

You can use IS_ENABLED(CONFIG_USB) instead of these two now. WBR, Sergei -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
