commit 43855ac61483cb914f060851535ea753c094b3e0 upstream.
The driver generates following warning when regulator support isn't enabled in the kernel. Fix it.
drivers/cpufreq/s3c64xx-cpufreq.c: In function 's3c64xx_cpufreq_set_target':
drivers/cpufreq/s3c64xx-cpufreq.c:55:22: warning: variable 'old_freq' set but not used [-Wunused-but-set-variable]
55 | unsigned int old_freq, new_freq; | ^~~~~~~~
drivers/cpufreq/s3c64xx-cpufreq.c:54:30: warning: variable 'dvfs' set but not used [-Wunused-but-set-variable]
54 | struct s3c64xx_dvfs *dvfs; | ^~~~
