Arnd, Krzysztof commented its fix has been submitted and landed in my 
-test tree not -next because it should be handled in rmk's tree I think.

I sent the patch to RMK patch tracking system just now and it should be 
fine in there.

BTW, I just applied the fix in my -next until its ladning in RMK tree 
but as you know it will be not be sent to arm-soc via samsung tree...

One more, Arnd please pull my pull-request 2nd round and 3rd round for 
samsung stuff for 3.18.
