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->[pm/tplg] == NULL (treated optional for pm currently) sdev->ipc->ops->[pm/tplg]->ops == NULL (treated optional currently) Signed-off-by: Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx> Reviewed-by: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx> Reviewed-by: Ranjani Sridharan <ranjani.sridharan@xxxxxxxxxxxxxxx> Reviewed-by: Bard Liao <yung-chuan.liao@xxxxxxxxxxxxxxx> Reviewed-by: Rander Wang <rander.wang@xxxxxxxxx> --- sound/soc/sof/pm.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/sound/soc/sof/pm.c b/sound/soc/sof/pm.c index df740be645e8..e7fce9e4a0d2 100644 --- a/sound/soc/sof/pm.c +++ b/sound/soc/sof/pm.c @@ -73,8 +73,8 @@ static void sof_cache_debugfs(struct snd_sof_dev *sdev) static int sof_resume(struct device *dev, bool runtime_resume) { struct snd_sof_dev *sdev = dev_get_drvdata(dev); - const struct sof_ipc_pm_ops *pm_ops = sdev->ipc->ops->pm; - const struct sof_ipc_tplg_ops *tplg_ops = sdev->ipc->ops->tplg; + const struct sof_ipc_pm_ops *pm_ops = sof_ipc_get_ops(sdev, pm); + const struct sof_ipc_tplg_ops *tplg_ops = sof_ipc_get_ops(sdev, tplg); u32 old_state = sdev->dsp_power_state.state; int ret; @@ -155,7 +155,7 @@ static int sof_resume(struct device *dev, bool runtime_resume) } /* restore pipelines */ - if (tplg_ops->set_up_all_pipelines) { + if (tplg_ops && tplg_ops->set_up_all_pipelines) { ret = tplg_ops->set_up_all_pipelines(sdev, false); if (ret < 0) { dev_err(sdev->dev, "Failed to restore pipeline after resume %d\n", ret); @@ -179,8 +179,8 @@ static int sof_resume(struct device *dev, bool runtime_resume) static int sof_suspend(struct device *dev, bool runtime_suspend) { struct snd_sof_dev *sdev = dev_get_drvdata(dev); - const struct sof_ipc_pm_ops *pm_ops = sdev->ipc->ops->pm; - const struct sof_ipc_tplg_ops *tplg_ops = sdev->ipc->ops->tplg; + const struct sof_ipc_pm_ops *pm_ops = sof_ipc_get_ops(sdev, pm); + const struct sof_ipc_tplg_ops *tplg_ops = sof_ipc_get_ops(sdev, tplg); pm_message_t pm_state; u32 target_state = 0; int ret; @@ -277,7 +277,7 @@ static int sof_suspend(struct device *dev, bool runtime_suspend) int snd_sof_dsp_power_down_notify(struct snd_sof_dev *sdev) { - const struct sof_ipc_pm_ops *pm_ops = sdev->ipc->ops->pm; + const struct sof_ipc_pm_ops *pm_ops = sof_ipc_get_ops(sdev, pm); /* Notify DSP of upcoming power down */ if (sof_ops(sdev)->remove && pm_ops && pm_ops->ctx_save) -- 2.39.0
