[alsa-devel] [PATCH 1/2] ASoC: add api for dapm kcontrol configiuration

[Vinod Koul]

From: Subhransu S. Prusty <subhransu.s.prusty at intel.com>

For DSPs we need to set and get the value for snd_kcontrol. This is currently
done by dapm_kcontrol_set/get_value, so create a wrapper
snd_soc_dapm_kcontrol_get/set_value APIs to let drivers use this
