<div class='commit-subject'>ARM: cpuidle: Pass on arm_cpuidle_suspend()'s return value</div><div class='commit-msg'>arm_cpuidle_suspend() may return -EOPNOTSUPP, or any value returned
by the cpu_ops/cpuidle_ops suspend call. arm_enter_idle_state() doesn't
update 'ret' with this value, meaning we always signal success to
cpuidle_enter_state(), causing it to update the usage counters as if we
succeeded.
