[PATCH 02/16] intel_idle: Fix a helper function's return value.

[Tim Gardner]

From: Richard Cochran <rcochran at linutronix.de>

BugLink: http://bugs.launchpad.net/bugs/1591821

The function, intel_idle_cpuidle_driver_init, delivers no error codes
at all.  This patch changes the function to return 'void' instead of
returning zero.
