Maybe I'm trying to be too clever for my own good, but my reasoning was as follows: Suppose I newly use the of_graph_ helpers in a subsystem that does not yet select OF_GRAPH. In that case I'd rather get linking errors earlier rather than stubbed out functions that silently fail to parse the DT later. Since there is config VIDEO_DEV select OF_GRAPH if OF already and the same should be added for other users of device tree graphs, I think stubbing out the functions only if OF is disabled should be enough. regards Philipp -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
