Subject: cpufreq: governors: Move get_governor_parent_kobj() to cpufreq.c
X-Git-Tag: upstream/snapshot3+hdmi~4790^2~1^2~5^2~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=944e9a0316e60bc5bc122e46c1fde36e5f6e9f56;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

cpufreq: governors: Move get_governor_parent_kobj() to cpufreq.c

get_governor_parent_kobj() can be used by any governor, generic
cpufreq governors or platform specific ones and so must be present in
cpufreq.c instead of cpufreq_governor.c.

This patch moves it to cpufreq.c. This also adds
EXPORT_SYMBOL_GPL(get_governor_parent_kobj) so that modules can use
this function too.
