Subject: [POWERPC] pasemi: Move pasemi_idle_init() to late_initcall()
X-Git-Tag: firefly_0821_release~26066^2~273
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3850169dbddcc9e53fd550eb093af7da5dfcefa9;p=firefly-linux-kernel-4.4.55.git

[POWERPC] pasemi: Move pasemi_idle_init() to late_initcall()

Move pasemi_idle_init() to be a late_initcall instead of being called from
setup_arch().  This way the cpufreq driver has a chance to initialize and
save away the boot time astate before we go to idle for the first time.
