If you look in cistpl_funce_func() you'll find this code:

        vsn = func->card->cccr.sdio_vsn;
        min_size = (vsn == SDIO_SDIO_REV_1_00) ? 28 : 42;
        if (size < min_size || buf[0] != 1)
                return -EINVAL;

I suspect your card might be buggy wrt the SDIO standard.

You could try printing out the value of vsn here, and then hardcode it 
to SDIO_SDIO_REV_1_00 to see if that helps.
