Subject: [PATCH 4.2.y-ckt 28/59] ARM: cpuidle: Pass on arm_cpuidle_suspend()'s return value
Date: Mon, 9 May 2016 12:55:46 -0700 [thread overview]
Message-ID: <1462823777-8384-29-git-send-email-kamal@canonical.com> (raw)
In-Reply-To: <1462823777-8384-1-git-send-email-kamal@canonical.com>
4.2.8-ckt10 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: James Morse <james.morse@arm.com>
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.
Fixes: 191de17aa3c1 ("ARM64: cpuidle: Replace cpu_suspend by the common ARM/ARM64 function")
