Subject: [PATCH] USB: gadget: Rename usb_gadget_probe_driver()
Git-commit: af1969a2d734d6272c0640b50c3ed31e59e203a9
References: jsc#PED-1817
Patch-mainline: v5.19-rc1

In preparation for adding a "gadget" bus, this patch renames
usb_gadget_probe_driver() to usb_gadget_register_driver().  The new
name will be more accurate, since gadget drivers will be registered on
the gadget bus and the probing will be done by the driver core, not
the UDC core.
