ASoC: dapm: Modify widget stream name according to prefix
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 Signed-off-by: Koro Chen <koro.chen@mediatek.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
