ASoC: Intel: Clear stored Baytrail DSP DMA pointer before stream start
Stored DSP DMA pointer must be cleared before starting the stream since PCM pointer callback sst_byt_pcm_pointer() can be called before pointer is updated. In that case last position of previous stream was wronly returned. Signed-off-by: Jarkko Nikula <jarkko.nikula@linux.intel.com> Signed-off-by: Mark Brown <broonie@linaro.org>
