This series solves a problem which does not exist in reality and is
only theoretic.
The devices are instantiated from their init functions which always
adds the resource.
Please do not submit such patches.
As you said the resource will be add in init functions, I checked these
drivers, the driver
sch5627 and sch5636 won't add resource, so need I send patches to fix
these drivers ?
Thanks,
