Thanks. This is actually a candidate for current v4.3 cycle. It fixes
issue with LEDs for Odroid XU3 caused by Anand's b685d540cc26:
The offending commit b685d540cc26 was merged in v4.3.
I forgot to add "fixes" tag.
	Fixes: b685d540cc26 ("ARM: dts: Add pwm-fan node for exynos5422-odroidxu3")

Can you send it to arm-soc during this cycle?

For current v4.3 Bartlomiej's patch is also an important candidate:
"ARM: dts: add suspend opp to exynos4412"

Best regards,
Krzysztof
