 System pin control hogging
 ==========================
 
-A system pin control map entry, i.e. a pin control setting that does not have
-a device associated with it, can be hogged by the core when the pin controller
+Pin control map entries can be hogged by the core when the pin controller
 is registered. This means that the core will attempt to call pinctrl_get() and
 pinctrl_enable() on it immediately after the pin control device has been
 registered.
