ACPI / processor: Drop unused variable from processor_perflib.c
The count variable in acpi_processor_preregister_performance() is only initalized as 1 for one CPU and incremented when another CPU sharing the same dependency domain is found. It isn't referenced anywhere else, so drop it. Signed-off-by: Lan Tianyu <tianyu.lan@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
