From 008f4d9e3cd666c1c4f97b53c102a868a6041f64 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Thu, 24 Jul 2014 12:51:26 -0700 Subject: Input: wacom - split out the pad device for the wireless receiver The Wireless Receiver should also behave in the same way than regular USB devices. To simplify the unregistering of the different devices, wacom_unregister_inputs() is introduced. For consistency, the function wacom_register_input() is renamed into wacom_register_inputs().
