My initial PR didn't have this remove_no_wq() callback.
For symmetry it could be useful if it is meant to undo what the
probe_no_wq() did, but conceptually the first thing we do in the remove
is make sure that workqueue is either not scheduled or we wait until it
completes.
int snd_sof_device_remove(struct device *dev)
{
struct snd_sof_dev *sdev = dev_get_drvdata(dev);
struct snd_sof_pdata *pdata = sdev->pdata;
int ret;
if (IS_ENABLED(CONFIG_SND_SOC_SOF_PROBE_WORK_QUEUE))
cancel_work_sync(&sdev->probe_work);
