[PATCH] documentation: Format button_dev as a pointer.

[Nelson Penn <nelsonapenn@protonmail.com>]

The docs on creating an input device driver have an example in which
button_dev is a pointer to an input_dev struct. However, in two code
snippets below, button_dev is used as if it is not a pointer. Make these
occurrences of button_dev reflect that it is a pointer.

 type events, and from those only BTN_0 event code. Thus we only set these
 two bits. We could have used::

-	set_bit(EV_KEY, button_dev.evbit);
-	set_bit(BTN_0, button_dev.keybit);
+	set_bit(EV_KEY, button_dev->evbit);
+	set_bit(BTN_0, button_dev->keybit);

 as well, but with more than single bits the first approach tends to be
 shorter.

 Then the example driver registers the input device structure by calling::

-	input_register_device(&button_dev);
+	input_register_device(button_dev);

 This adds the button_dev structure to linked lists of the input driver and
 calls device handler modules _connect functions to tell them a new input
