That's not a good warning because it's a meaningless string and you're passing
the error number to the dev%d.

Better would perhaps be:

	"dev%d: Failed to create physical_node sysfs link: %d\n"

Note also that you're only checking the result of one sysfs_create_link().
You should probably check both.

Also you're introducing a pair of unnecessary braces as there's only one
statement in the if-body.
