## Overview

In the Linux kernel, the following vulnerability has been resolved:

HID: rapoo: fix missing hid_is_usb() check

to_usb_interface() can only be used on a hid_device whose parent is really
USB; uhid can create devices that identify as being on BUS_USB, but don't
actually have a USB parent.
Fix the use of to_usb_interface() without a hid_is_usb() check.

Add a dependency on USB_HID for hid_is_usb(), as other HID drivers do; the
alternative would be to provide a simple stub implementation on !USB_HID
builds.

I have verified that it is currently possible to trigger a kernel splat due
to this bug in an ASAN build, and that this commit fixes the issue.
