Well, they are not really useful because they are actually undocumented.

Rather print version and KEY_MAP_VER

Rather print key_data_len + SHIFT_TBL_SIZE + 4 and sizeof(spk_key_buf)

Rather print ch and SHIFT_TBL_SIZE.

Rather print ch and MAX_KEY.

Apart from that, returning -EINVAL instead of different values is fine
