From 7ced4810f9a86bb0324568052c6bf27292512b43 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 2 Mar 2011 18:28:52 -0800 Subject: [PATCH] Staging: hv: hv_mouse: unwind the initialization process a bit This unwinds the init call sequence a bit, as we don't need a callback pointer for a function that is already in this file.
