Hi Rafael and Viresh,
Since this is a fix to prevent memory leak, it would be better if
this could be sent to linus during -rc via cpufreq tree.
Thanks,
Kukjin

I'm not planning more pull requests for 4.2 and this one doesn't seem to be
a good enough reason for a pull request of its own, though.
Of course, if there are more urgent fixes, I can push it along with them,
but there are none so far.
Thanks,
Rafael

The cpufreq driver will be removed completely in v4.3 or v4.4 with
patchset adding cpufreq-dt support for Exynos 4x12. This means that this
patch makes sense only for 4.2 and as a stable backport (but it was not
marked as such).
Anyone thinks that the patch will be worth stable back-porting?
Best regards,
Krzysztof

Since I have one more ACPI fix for 4.2, I've applied this one and will
push it to Linus next week.
