Ah, here you have. No one expected this... Order your patches correctly.
User cannot be before documentation.

Please run scripts/checkpatch.pl and fix reported warnings. Some
warnings can be ignored, but the code here looks like it needs a fix.
Feel free to get in touch if the warning is not clear.

Runnign checkpatch should be a must before sending a patches.
