Subject: thermal: cpu_cooling: Merge cpufreq_apply_cooling() into cpufreq_set_cur_state()
X-Git-Tag: v5.15~16590^2^2~1^2~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5194fe469927e50367b35e556812c7fc6ce130d1;p=platform%2Fkernel%2Flinux-starfive.git

thermal: cpu_cooling: Merge cpufreq_apply_cooling() into cpufreq_set_cur_state()

cpufreq_apply_cooling() has a single caller, cpufreq_set_cur_state() and
cpufreq_set_cur_state() is an unnecessary wrapper over cpufreq_apply_cooling().

Get rid of it by merging both routines.
