These adapters allow pre-USB Sun keyboards to be connected to USB-only
machines, but includes the wrong maximum keycode in its report
descriptor, making most of the keys present on Sun keyboards but not
101-key PC keyboards nonfunctional.
This patch implements a quirk that overrides the maximum keycode in the
report descriptor.

No need to depend on USB_HID. Your driver is just using the plain HID
protocol, so the guard "if HID" at the beginning of the Kconfig is
sufficient.

You can use module_hid_driver(nti_driver); and remove both nti_init()
and nti_exit().
Rest looks good to me.

Actually, aren't you missing MODULE_AUTHOR and MODULE_DESCRIPTION?
