[PATCH 5.10 623/663] cpufreq: intel_pstate: Change intel_pstate_get_hwp_max() argument

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

commit a45ee4d4e13b0e35a8ec7ea0bf9267243d57b302 upstream.

All of the callers of intel_pstate_get_hwp_max() access the struct
cpudata object that corresponds to the given CPU already and the
function itself needs to access that object (in order to update
hwp_cap_cached), so modify the code to pass a struct cpudata pointer
to it instead of the CPU number.
