+Subject: [PATCH] cpufreq/aperf : fix the /proc/stat read routine, always fails otherwise.
+
+ the statement:
+ if (!fgets(value, LINE_LEN, fp)) {
+ always fails(==0) at the end of proc file, so we will have err_out:
+ firing all the time.
+
+ I've aligned the code to the one that other utils of cpufreq has.
