When I try to compile with TWL6030_USB=y, TWL4030_USB=y and
USB_MUSB_OMAP2PLUS=m, I get the following error:

drivers/built-in.o: In function `twl4030_usb_irq':
/home/xxx/kernel/linux/drivers/usb/otg/twl4030-usb.c:518: undefined

make: *** [vmlinux] Error 1

To solve this we must add to depends of TWL4030_USB and TWL6030_USB
the option : USB_MUSB_OMAP2PLUS as done here.
