There is a small warning in the 3rd patch, how do you suggest we fix that,
should I post a new version or you'll modify the patch at your end?

drivers/cpufreq/amd-pstate.c: In function 'amd_pstate_epp_offline':
>> drivers/cpufreq/amd-pstate.c:1664:13: warning: variable 'value' set but not used [-Wunused-but-set-variable]
1664 | u64 value;
| ^~~~~
