Subject: [PATCH v2 2/9] POWERPC: pseries: cpuidle: remove superfluous dev->state_count initialization
Date: Fri, 20 Dec 2013 19:47:24 +0100	[thread overview]
Message-ID: <1387565251-7051-3-git-send-email-b.zolnierkie@samsung.com> (raw)
In-Reply-To: <1387565251-7051-1-git-send-email-b.zolnierkie@samsung.com>

pseries cpuidle driver sets dev->state_count to drv->state_count so
the default dev->state_count initialization in cpuidle_enable_device()
(called from cpuidle_register_device()) can be used instead.
