If anyone has any objections, please let me know. ------------------ From: Koro Chen 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 Signed-off-by: Koro Chen Signed-off-by: Mark Brown Signed-off-by: Kamal Mostafa --- sound/soc/soc-dapm.c | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) diff --git a/sound/soc/soc-dapm.c b/sound/soc/soc-dapm.c index c5136bb..9d56b0b 100644 --- a/sound/soc/soc-dapm.c +++ b/sound/soc/soc-dapm.c @@ -3073,11 +3073,16 @@ snd_soc_dapm_new_control(struct snd_soc_dapm_context *dapm, } prefix = soc_dapm_prefix(dapm); - if (prefix) + if (prefix) { w->name = kasprintf(GFP_KERNEL, "%s %s", prefix, widget->name); - else + if (widget->sname) + w->sname = kasprintf(GFP_KERNEL, "%s %s", prefix, + widget->sname); + } else { w->name = kasprintf(GFP_KERNEL, "%s", widget->name); - + if (widget->sname) + w->sname = kasprintf(GFP_KERNEL, "%s", widget->sname); + } if (w->name == NULL) { kfree(w); return NULL; -- 1.9.1
