From: Lee Jones <lee@xxxxxxxxxx> commit 1c5d4221240a233df2440fe75c881465cdf8da07 upstream. The default maximum data buffer size for this interface is UHID_DATA_MAX (4k). When data buffers are being processed, ensure this value is used when ensuring the sanity, rather than a value between the user provided value and HID_MAX_BUFFER_SIZE (16k).
