Subject: cpufreq: acpi-cpufreq: Simplify boost-related code
X-Git-Tag: v4.14-rc1~3904^2^3~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=17135782b816383b426d280c350467b23ef9c10c;p=platform%2Fkernel%2Flinux-rpi.git

cpufreq: acpi-cpufreq: Simplify boost-related code

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.
