+ * \brief Try to read a device firmware ID from sysfs

+ * The ID recorded in the devices firmware description is recorded differently

+ *
+ * For OF-based systems the ID is the full path of the device in the device tree
+ * description. For ACPI-based systems the ID is the ACPI firmware nodes path.
+ * Both ID sources are guaranteed to be unique and persistent as long as the
+ * firmware of the system is not changed.
