We call cpufreq_cpu_get() in cpufreq_add_dev_symlink() to increase usage refcount of policy and not to get policy for a cpu. So, we don't really need to capture the return value of this routine and call put for it later for failure cases. We can simply use policy passed as an argument to this routine. Moreover debug print is rewritten to make it more clear. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
Both [1-2/2] look good, but what do they apply to? Mainline, linux-next, my bleeding-edge branch? Rafael
