From: Jisheng Zhang Date: Tue, 22 Mar 2016 14:42:41 +0000 (+0800) Subject: ARM: cpuidle: constify return value of arm_cpuidle_get_ops() X-Git-Tag: Ubuntu-5.4-5.4.0-11.14~10183^2~3^2^2~2^2~2 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=4cfd55202cee115a3686d5ad6a0f60d604aca802;p=mirror_ubuntu-focal-kernel.git 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.
