ASoC: dapm: Modify widget stream name according to prefix
[ Upstream commit fdb6eb0a12871d5bfaf266c5a0d5259a5437a72f ]
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
