Even if USB_PHY is not selected, the functions (except > usb_add/remove_phy() are defined as inlines in /include/linux/usb/phy.h If CONFIG_USB is set to M you should see the problem since EHCI-OMAP would 'select' (meaning set Y) to the PHY driver. Kbuild won't statically link anything from a directory which was entered due to M. Not sure if that sounds as clear as I expected :-p -- balbi
