From 71f1309f4f5b70aa3f1342a52b1460aa454c39ff Mon Sep 17 00:00:00 2001 From: Yue Hu Date: Thu, 18 Feb 2021 17:01:32 +0800 Subject: cpufreq: schedutil: Remove needless sg_policy parameter from ignore_dl_rate_limit() Since sg_policy is a member of struct sugov_cpu. Also remove the local variable in sugov_update_single_common() to make the code more clean. Signed-off-by: Yue Hu Acked-by: Viresh Kumar [ rjw: Minor subject edits ] Signed-off-by: Rafael J.
