What is wrong with calling it gadget controller?

   It's not a controller, it's a piece of software AFAIU. Or is my English just too weak? :-)

Everything at this point is a piece of software :).

struct usb_gadget, represents the gadget controller device not the
driver (or software).

struct usb_gadget_driver represents the gadget function driver.
struct usb_gadget_ops represents the UDC driver ops.

right, and usb_udc was added just to have a way of linking usb_gadget
with usb_gadget_driver so we could have more than one peripheral port in
a system.
