ASoC: DAPM: Fix missing kctl change notifications
commit 5af82c81b2c49cfb1cad84d9eb6eab0e3d1c4842 upstream.
The put callback of a kcontrol is supposed to return 1 when the value
is changed, and this will be notified to user-space. However, some
DAPM kcontrols always return 0 (except for errors), hence the
user-space misses the update of a control value.
This patch corrects the behavior by properly returning 1 when the
value gets updated.
