Okay I do not know the details, but that doesn't sound correct to me. Breaking build sounds a bit extreme to me.

If you are depedent upon a symbol provided by a module you should say depends on. If a machine is not supposed to have both SMD or GLINK then the driver will not get probed. -- ~Vinod -- 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
