pub type DeviceLabel = u32;Expand description
A device label is a development-time fixed identifier that can be used hardcoded in the source code in order to identify declared device. This label is, by now, the result of the device tree analysis but will be replaced by a clean outpost,label field at dts level, in the same way other label are set, to highly simplify userspace level usage. This label is used to get back the associated handle at run time.
