Subject: ARM: cpuidle: Pass on arm_cpuidle_suspend()'s return value
From: James Morse <[email protected]>
commit 625fe4f8ffc1b915248558481bb94249f6bd411c upstream.
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.
