From cce2dbdf258e6b27b2b100f511531edabb77f427 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Tue, 3 Mar 2015 12:44:02 -0500 Subject: [PATCH] HID: uclogic: name the input nodes based on their tool We append "Pen", "Pad", "Mouse", "Keyboard", "Consumer Control" or "System Control" suffix to the appropriate input node to match what the Wacom driver does and be more convenient for the user to know which one is which.
