Is this name supposed to be identical with the string the patch 1 sets? If so, this looks incompatible.
Also, it'd be easier to parse the string only once like:
int bus_idx, addr;
if (sscanf(codec_name, "ehdaudio%dD%d", &bus_idx, &addr) != 2) return NULL; if (ebus->index != bus_idx) return NULL; list_for_each_entry(hlink, &ebus->hlink_list, list) if (hlink->lsdiid && (0x1 << addr)) return hlink;
return NULL;
