The IPC ops are optional, but they require that the ops struct is to be allocated with all callbacks set to NULL. Update the code to extend the optionality to: sdev->ipc == NULL sdev->ipc->ops == NULL sdev->ipc->ops->[tplg] == NULL sdev->ipc->ops->[tplg]->control == NULL sdev->ipc->ops->[tplg]->control->ops == NULL (treated optional currently) Signed-off-by: Peter Ujfalusi <peter.ujfalusi@linux.intel.com> Reviewed-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Reviewed-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com> Reviewed-by: Bard Liao <yung-chuan.liao@linux.intel.com> Reviewed-by: Rander Wang <rander.wang@intel.com> Link: https://lore.kernel.org/r/20221221102328.9635-6-peter.ujfalusi@linux.intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
