Subject: [PATCH] cpufreq: schedutil: Make it depend on CONFIG_SMP

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
Subject: [PATCH] cpufreq: schedutil: Make it depend on CONFIG_SMP

Make the schedutil cpufreq governor depend on CONFIG_SMP, because
the scheduler-provided utilization numbers used by it are only
available for CONFIG_SMP set.

Fixes: 9bdcb44e391d (cpufreq: schedutil: New governor based on scheduler utilization data)
