Subject: [for-next][PATCH 4/6] trace/osnoise: Fix return value on osnoise_init_hotplug_support

From: Daniel Bristot de Oliveira <bristot@...hat.com>

kernel test robot reported:

  >> kernel/trace/trace_osnoise.c:1584:2: error: void function
  'osnoise_init_hotplug_support' should not return a
  value [-Wreturn-type]
           return 0;

When !CONFIG_HOTPLUG_CPU.

Fix it problem by removing the return value.
