[PATCH 0/2] __cpuhp_setup_state() returns positive value for dynamic state

[Boris Ostrovsky]

The first patch corrects description of __cpuhp_setup_state()'s possible
return values and the second fixes a bug (which causes Xen guests to crash).

As a follow-up question for the first patch --- should we allow calling
__cpuhp_setup_state() with state in [CPUHP_AP_ONLINE_DYN + 1 .. CPUHP_AP_ONLINE_DYN_END]
range?

Boris Ostrovsky (2):
  cpu/hotplug: Clarify description of __cpuhp_setup_state() return
    value
  cpufreq: Remove cpu hotplug callbacks only if they were initialized
