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.
