Either way: > > Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Hi Daniel, unbind undo what has been done in bind even the functions aren't symetric: encoder creation are done is this level of the driver while they destruction is done in the top level of the driver by calling drm shutdown function. From module point of view bind and unbind are balanced correctly. I have test it on board :-) I will not merge this patch until I get a clear review from you.
