+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.
