ASoC: core: Add flag to ignore pmdown_time at pcm_close
With this flag codec drivers can indicate that it is desired to ignore the pmdown_time for DAPM shutdown sequence when playback stream is stopped. The DAPM sequence will be executed without delay in this case. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
