From 1a5d76dbe825fa6deba3d8979bbd334ea17b6dcc Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Sat, 8 Dec 2012 15:38:06 -0200 Subject: [PATCH] drivers/base/core.c: Remove two unused variables and two useless calls to kfree old_class_name, and new_class_name are never used. This patch remove the declaration and calls to kfree.
