Please cc me on fw_devlink patches. Also, this patch is breaking the

All the simple properties are listed before the suffix ones as the
suffix checks are more expensive. So, you should have inserted this
right before the suffix properties. Also, there's a merge conflict in
linux-next. So make sure you take that into account when sending the
fix up and picking the order.
