[PATCH master] of: partition: do not try to translate offset as OF address

[PATCH master] of: partition: do not try to translate offset as OF address

[Ahmad Fatoum]

of_platform_populate will eventually call of_platform_device_create,
which will print out errors, because of_translate_address chokes on the
partitions node.

The correct fix would be not to use a platform bus here, but until we
add something like the fauxbus, just opencode the platform device
creation without the address translation parts.
