Subject: [PATCH] subclassing devices - fix put_image method
The subclassing devices need to change the 'memory device' parameter to
be the child device, when its the same as the subclassing device.
Otherwise we end up trying to access the child device's memory pointers
in the subclassing device, which may not contain valid copies of
those pointers.
