platform_add_device()
According to "git grep" this function is not present in 6.6-rc2.
If you mean platform_device_add(), please update the patch subject and changelog accordingly.
creates the numa_node attribute of sysfs according to whether dev_to_node(dev) is equal to NUMA_NO_NODE. So set the numa node of device before creating numa_node attribute of sysfs.
It would be good to also say that this needs to be done in platform_device_register_full(), because that's where the platform device object is allocated.
However, what about adding the NUMA node information to pdevinfo? It would be more straightforward to handle it then AFAICS.
