We haven't ensured the adpt->iface == iface.

Probably you want to say:
list_for_each_entry(adpt, &adpt_list, list) {
if (adpt->iface != iface)
continue;
if (adpt->registered)
return -ENOSPC;
adpt->pcm_dev_idx++;
goto skip_adpt_alloc;
}
But here again, I think I might prefer if allocating a new "adpt" were
and explicit command from user space as opposed to just a side effect of
registering a new iface.
