[PATCH 2/3] cpufreq: acpi-cpufreq: Simplify boost-related code

From: Rafael J. Wysocki
Date: Sat Dec 26 2015 - 17:57:29 EST


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

The store_boost() routine is only used by store_cpb(), so move
the code from it directly to that function and rename _store_boost()
to set_boost() to make its name reflect the name of the driver
callback pointing to it.
