+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.
