Subject: cpuidle: make __cpuidle_driver_init() return void
X-Git-Tag: v3.13-rc1~96^2~5^2~12
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=e437f3e37369606bf1a340e0504554d6530abc51;p=linux.git

cpuidle: make __cpuidle_driver_init() return void

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