| |
When the k3 socinfo driver is built as a module, there is a possibility that it will probe after the k3 udma driver and the later returns -ENODEV. By deferring the k3 udma probe we allow the k3 socinfo to probe and register the soc_device_attribute structure needed by the k3 udma driver. Removed the dev_err() message as well as it's deferring and not failing.
