I guess...

Although this reads really non-sensical. But it looks like enforcing the
state of the dependent symbol is being done in other places so please
add a comment similar to like it is done in those other places so that
it is clear:

drivers/usb/phy/Kconfig:25: depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, this can't be 'y'
drivers/usb/phy/Kconfig:34: depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, this can't be 'y'
drivers/usb/phy/Kconfig:57: depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, NOP can't be built-in
drivers/usb/phy/Kconfig:93: depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, this can't be 'y'
...

Thx.
