Subject: [PATCH v2 2/9] POWERPC: pseries: cpuidle: remove superfluous
 dev->state_count initialization

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.
