From: Su Hui Date: Wed, 30 Apr 2025 03:27:32 +0000 (+0800) Subject: time/jiffies: Change register_refined_jiffies() to void __init X-Git-Tag: v6.16-rc1~183^2~4 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=007c07168ac0c64387be500f6604b09ace3f3bdc;p=thirdparty%2Flinux.git time/jiffies: Change register_refined_jiffies() to void __init register_refined_jiffies() is only used in setup code and always returns 0. Mark it as __init to save some bytes and change it to void.
