Subject: [PATCH] cpuidle: ladder governor - use macro instead of hardcoded value
Date: Mon, 28 Jul 2014 09:58:50 +0600	[thread overview]
Message-ID: <1406519930-5159-1-git-send-email-meraj.enigma@gmail.com> (raw)

use CPUIDLE_DRIVER_STATE_START, instead of hardcoded value 0. As,
CPUIDLE_DRIVER_STATE_START can be 1/0 based on
CONFIG_ARCH_HAS_CPU_RELAX is defined or not.
