Subject: ANDROID: cpufreq: dt: invoke frequency-invariance setter function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=768aa8c4c5b0f064367d8f33dd1a1a545a180160;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ANDROID: cpufreq: dt: invoke frequency-invariance setter function

Call the frequency-invariance setter function arch_set_freq_scale()
if the new frequency has been successfully set which is indicated by
dev_pm_opp_set_rate() returning 0.
