ASoC: SOF: topology: cleanup dailinks on widget unload
We set the cpu_dai capture_ or playback_widget on widget_ready but never clear them, which leads to failures when unloading/reloading a topology in modprobe/rmmod tests BugLink: https://github.com/thesofproject/linux/issues/3535 Fixes: 311ce4fe7637 ("ASoC: SOF: Add support for loading topologies") Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Reviewed-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com> Reviewed-by: Péter Ujfalusi <peter.ujfalusi@linux.intel.com> Reviewed-by: Bard Liao <yung-chuan.liao@linux.intel.com> Link: https://lore.kernel.org/r/20220406191606.254576-1-pierre-louis.bossart@linux.intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
