Jiri Kosina	59579a8d17	HID: u2fzero: fail probe if not using USB transport ... u2fzero driver is USB-only. Therefore we have to give up in ->probe() callback in case we're called with non-USB transport driver bound, otherwise the kernel will crash trying to use USBHID API on a non-USB transport.

Andrej Shadura	42337b9d4d	HID: add driver for U2F Zero built-in LED and RNG ... U2F Zero supports custom commands for blinking the LED and getting data from the internal hardware RNG. Expose the blinking function as a LED device, and the internal hardware RNG as an HWRNG so that it can be used to feed the enthropy pool.
