The above patchset contains pwm-fan specific patch:
"[PATCH v2 3/3] hwmon: pwm-fan: remove no longer needed suspend/resume code"
(https://www.spinics.net/lists/kernel/msg2495210.html).

It seems that the patchset name itself could be better,
sorry for this.

Yes, on Exynos5422 based Odroid-XU3 board.
