Currently there is no dependency between the "linaro,scmi-optee" driver and the tee_core. If the scmi-optee driver gets probed before the tee_bus_type is initialized, then we will get an unwanted error print.
What error print do you observe? I suppose this case is already handled by scmi optee driver via -EPROBE_DEFER.

This patch enables putting scmi-optee nodes as children to the optee node in devicetree, which indirectly creates the missing dependency.
