HID: wacom: fix problems when device is not a valid USB device
stable inclusion from stable-v5.10.85 commit 889c39113f7e2219da49446b7e8772d1f62d0dca bugzilla: 186032 https://gitee.com/openeuler/kernel/issues/I4QVI4 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=889c39113f7e2219da49446b7e8772d1f62d0dca -------------------------------- commit 720ac467 upstream. The wacom driver accepts devices of more than just USB types, but some code paths can cause problems if the device being controlled is not a USB device due to a lack of checking. Add the needed checks to ensure that the USB device accesses are only happening on a "real" USB device, and not one on some other bus.
