X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c99e720a71216066565d7cf6fb2940b3bd504efd;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ANDROID: cpufreq: arm_big_little: 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
bL_cpufreq_set_rate() returning 0.
