From a59e5109f648f703d877d3c33cc5a7ef283dba83 Mon Sep 17 00:00:00 2001 From: Prarit Bhargava Date: Sun, 14 Dec 2014 09:06:38 -0500 Subject: [PATCH] tools / cpupower: Fix no idle state information return value sysfs_get_idlestate_count() returns an unsigned int. Returning -ENODEV is not the right thing to do here, and in any case is handled the same way as if there are no states found.
