http://marc.info/?l=linux-kernel&m=119940325306693&w=2

Checkpatch before the patch:

	total: 3 errors, 13 warnings, 602 lines checked

Checkpatch after the patch:

	total: 0 errors, 1 warnings, 601 lines checked


1 Warning is still not killed:

Dunno whether the size change means that the patch is doing
something wrong but here it is the report, before and after 
the patch:
