cpufreq: amd-pstate: Fix min_perf assignment in amd_pstate_adjust_perf()
[ Upstream commit b26ffbf800ae3c8d01bdf90d9cd8a37e1606ff06 ]
In the function amd_pstate_adjust_perf(), the 'min_perf' variable is set
to 'highest_perf' instead of 'lowest_perf'.
Fixes: 1d215f0319c2 ("cpufreq: amd-pstate: Add fast switch function for AMD P-State")
