From 8c37d01e1a86073d15ea7084390fba58d9a1665f Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Thu, 17 Jun 2021 15:05:43 +0900 Subject: [PATCH] PM / devfreq: passive: Fix get_target_freq when not using required-opp The 86ad9a24f21e ("PM / devfreq: Add required OPPs support to passive governor") supported the required-opp property for using devfreq passive governor. But, 86ad9a24f21e has caused the problem on use-case when required-opp is not used such as exynos-bus.c devfreq driver. So that fix the get_target_freq of passive governor for supporting the case of when required-opp is not used.
