[Xen-devel] [PATCH v4 04/11] x86/intel_pstate: avoid calling cpufreq_add_cpu() twice

[Wei Wang <wei.w.wang@xxxxxxxxx>]

cpufreq_add_cpu() is already called in the hypercall code path
(the bottom of set_px_pminfo() and inside cpufreq_cpu_init()).
So, we remove the redundant calling here.

v4 changes:
None.
