[PATCH] HID: nintendo: Add missing array termination

From: Guenter Roeck
Date: Tue Jul 12 2022 - 18:17:19 EST


joycon_dpad_inputs_jc[] is unterminated. This may result in odd warnings
such as

input: input_set_capability: invalid code 3077588140 for type 1

or in kernel crashes in nintendo_hid_probe(). Terminate the array to fix
the problem.
