Subject: cpufreq: Retrieve current frequency from scaling drivers with internal governors
X-Git-Tag: v3.9-rc1~146^2~3^2~9
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9e21ba8bd849251c8ba22ddf39308a5227134fdc;p=pandora-kernel.git

cpufreq: Retrieve current frequency from scaling drivers with internal governors

Scaling drivers that implement the cpufreq_driver.setpolicy() versus
the cpufreq_driver.target() interface do not set policy->cur.

Normally policy->cur is set during the call to cpufreq_driver.target()
when the frequnecy request is made by the governor.

If the scaling driver implements cpufreq_driver.setpolicy() and
cpufreq_driver.get() interfaces use cpufreq_driver.get() to retrieve
the current frequency.
