> OK, and can you write what is needed to fill into buffer?

Here is the critical part of a working patch I prepared for
dell-laptop.c:

    get_buffer();
    buffer->input[0] =3D 0x10000;
    buffer->input[1] =3D 0x51534554;
    buffer->input[3] =3D 0x1;
    dell_send_request(buffer, 17, 3);
    ret =3D buffer->output[0];
    release_buffer();
