Date: Sun, 14 Dec 2014 09:06:38 -0500 From: Prarit Bhargava <prarit@...hat.com> To: linux-pm@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Prarit Bhargava <prarit@...hat.com>, Thomas Renninger <trenn@...e.de>, "Rafael J. Wysocki" <rafael.j.wysocki@...el.com> Subject: [PATCH 2/2] 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. Cc: Thomas Renninger <trenn@...e.de> Cc: Rafael J.
