Subject: cpuidle: make __cpuidle_device_init() return void
X-Git-Tag: upstream/snapshot3+hdmi~3917^2~5^2~14
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=267d4bf8ee6dbde889f4c55d0188f561616dbc7a;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

cpuidle: make __cpuidle_device_init() return void

The only value returned by __cpuidle_device_init() is 0, so it very
well may be a void function.  Make that happen.
