HID: lenovo-go: drop dead NULL check on to_usb_interface()
to_usb_interface() is a container_of_const() macro: it performs pointer arithmetic and never returns NULL. The if (!intf) and if (intf) tests in get_endpoint_address() can never fire. Remove them in both drivers. No functional change. Suggested-by: Derek J. Clark <derekjohn.clark@gmail.com> Signed-off-by: Louis Clinckx <clinckx.louis@gmail.com> Reviewed-by: Derek J.
