From 1a8e1463a49aaa452da1cefe184a00d4df47f1ef Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 4 May 2011 08:38:56 -0700 Subject: [CPUFREQ] remove redundant sprintf from request_module call. Since format string handling is part of request_module, there is no need to construct the module name. As such, drop the redundant sprintf and heap usage.
