4.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Koro Chen <koro.chen@mediatek.com>
commit fdb6eb0a12871d5bfaf266c5a0d5259a5437a72f upstream.
When there is prefix specified, currently we will add this prefix in widget->name, but not in widget->sname. it causes failure at snd_soc_dapm_link_dai_widgets:
if (!w->sname || !strstr(w->sname, dai_w->name))
because dai_w->name has prefix added, but w->sname does not. We should also add prefix for stream name
