+       help
+         This option enables the Managed device resources core support.
+         Device resources managed by the devres framework are automatically
+         released whether initialization fails half-way or the device gets
+         detached.
+
+         If this option is disabled, devres functions fall back to
+         non-managed variants.  For example, devres_alloc() to kzalloc(),
+         devm_kmalloc() to kmalloc(), etc.
