Subject[PATCH 2/3] cpufreq: governors: Move get_governor_parent_kobj() to cpufreq.c
Date
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.
