[media] ati_remote: Check the checksum An input report is 4 bytes long, but there are only 12 bits of actual payload. The 4 bytes are: data[0] = 0x14 data[1] = data[2] + data[3] + 0xd5 (a checksum byte) data[2] = the raw scancode (plus toggle bit in msbit) data[3] = channel << 4 (the low 4 bits must be zero) Ignore reports with a bad checksum.
