From 4cfd55202cee115a3686d5ad6a0f60d604aca802 Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Tue, 22 Mar 2016 22:42:41 +0800 Subject: [PATCH] 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.
