Subject: drivers/cpufreq: Convert some slow-path static_cpu_has() callers to boot_cpu_has()
X-Git-Tag: v5.15~6480^2~3^2~11^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=108ec36b699475001f5af81ff7db624427d14dbe;p=platform%2Fkernel%2Flinux-starfive.git

drivers/cpufreq: Convert some slow-path static_cpu_has() callers to boot_cpu_has()

Using static_cpu_has() is pointless on those paths, convert them to the
boot_cpu_has() variant.

No functional changes.
