This error is seen in build of type "minsize":
In function 'power_init_for_setting_freq',
drivers/power/intel_pstate/intel_pstate_cpufreq.c:205:30:
error: 'max_non_turbo' may be used uninitialized
[-Werror=maybe-uninitialized]
drivers/power/intel_pstate/intel_pstate_cpufreq.c:122:18:
note: 'max_non_turbo' was declared here
122 | uint64_t max_non_turbo;
It looks to be a compiler issue because we are not supposed
to reach this point in case of power_read_turbo_pct() failure.
The variable is initialized to allow compiling with "minsize" option.
