[PATCH 5.15 525/917] cpufreq: intel_pstate: Fix cpu->pstate.turbo_freq initialization

[Greg Kroah-Hartman]

From: Zhang Rui <rui.zhang@xxxxxxxxx>

[ Upstream commit c72bcf0ab87a92634e58af62e89af0f40dfd0b88 ]

Fix a problem in active mode that cpu->pstate.turbo_freq is initialized
only if HWP-to-frequency scaling factor is refined.

In passive mode, this problem is not exposed, because
cpu->pstate.turbo_freq is set again, later in
intel_cpufreq_cpu_init()->intel_pstate_get_hwp_cap().

Fixes: eb3693f0521e ("cpufreq: intel_pstate: hybrid: CPU-specific scaling factor")
