[PATCH] Fix uninitialized local variable "covered" in i386 acpi-cpufreq driver

From: Fenghua Yu
Date: Thu Jul 26 2007 - 19:52:27 EST


The local variable "covered" is used without initialization in i386 acpi-cpufreq
driver. The initial value of covered should be 0. The bug will cause memory leak
when hit. The following patch fixes this bug.
