- * xf86CollectInputOptions collects the options for an InputDevice.

- *
- *	pInfo->conf_idev
- *
- * The extraOpts parameter may optionally contain a list of additional options
- * to include.
- *
- * The order of precedence for options is:
- *
- *   extraOpts, pInfo->conf_idev->extraOptions,
- *   pInfo->conf_idev->commonOptions, defaultOpts
+ * xf86CollectInputOptions collects extra options for an InputDevice (other
+ * than those added by the config backend).
+ * The options are merged into the existing ones and thus take precedence
