And perhaps the interface should explicitly define that for the case where userspace sends an undersized scancode, the real scancode will be generated by zero-extending the undersized scancode into its expected size. That way the interface will be binary-forwards-compatible even if scancode sizes are increased at some later date. -- David Härdeman -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
