ASoC: component: Add sync_stop PCM ops
Add the support of the new PCM sync_stop ops in ASoC component. It's optional and can be NULL unless you need the sync operation. Acked-by: Mark Brown <broonie@kernel.org> Link: https://lore.kernel.org/r/20191121190709.29121-3-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
