Oops missed that part.
So am making it
if (type == SND_CTL_ELEM_TYPE_BYTES &&
(snd_ctl_elem_info_is_tlv_readable(info) ||
snd_ctl_elem_info_is_tlv_writable(info))) {
But this control can be read only or write only. Like a module doesnt allow
read, or some is read only so OR should be good here
Also should it check it is not normal read/write ?
Thanks
