Subject: cpufreq: governor: Drop cpu argument from dbs_check_cpu()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d10b5eb5fce436ba22443ab83eeb36e195dbf772;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

cpufreq: governor: Drop cpu argument from dbs_check_cpu()

Since policy->cpu is always passed as the second argument to
dbs_check_cpu(), it is not really necessary to pass it, because
the function can obtain that value via its first argument just fine.
