    Subject[PATCH 03/13] intel_idle: Fix a helper function's return value.
    Date
    From: Richard Cochran <rcochran@linutronix.de>

    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.
