Subject: raid6: generate raid6tables.c with proper style
From: Ingo Molnar <mingo@elte.hu>

nitpicking from the coding style police: generate a raid6tables.c that
does not show up in my editor all red ;-)

this also improves the code quality metric of drivers/md/ by
a factor of 10:

errors lines of code errors/KLOC
drivers/md/ [old] 9349 45543 205.2
drivers/md/ [new] 1062 45551 23.3

while humans are not likely to read that file, lets just do this to make
life easier for automated quality checking ...
