ARM: cpuidle: constify return value of arm_cpuidle_get_ops()
arm_cpuidle_read_ops() just copies '*ops' to cpuidle_ops[cpu], so the structure '*ops' is not modified at all. The comment is also updated accordingly. Signed-off-by: Jisheng Zhang <jszhang@marvell.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
