[PATCH] FIXED sparse warning : drivers/cpuidle/cpuidle.c:27:1: warning: symbol 'cpuidle_dev' was not declared. Should it be static?

This is the first (and minor) patch I am sending out, hope this is ok. I checked that cpuidle_devices is only being used in cpuidle.c - hence thought that it can be made static and be removed from header.
