ASoC: dapm: add a dapm sink widget
DAPM models various widgets but lacks a sink widget. DSPs can have modules which take audio data, process it and are capable of generating events thus acting as a sink of data. To make the dapm graph complete for such paths we need a dapm sink widget for these modules, so add a SND_SOC_DAPM_SINK to declare such a widget. This widget will be treated as SND_SOC_DAPM_EP_SINK endpoint in the dapm graph Signed-off-by: Vinod Koul <vinod.koul@intel.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
