Subject: [PATCH] cpufreq: Select IRQ_WORK if CPU_FREQ_GOV_COMMON is set

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Commit 8fb47ff100af (cpufreq: governor: Replace timers with utilization
update callbacks) made CPU_FREQ select IRQ_WORK, but that's not
necessary, as it is sufficient for IRQ_WORK to be selected by
CPU_FREQ_GOV_COMMON, so modify the cpufreq Kconfig to that effect.

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

On top of linux-next.

Thanks,
Rafael
