Where's the point of the enum if all values are initialized?

Enums start at 0 if not otherwise initialized and I wanted to keep the
unused 0th bit as unused in this patch, for either the patch from Jens
or 2/2 in this series.

It's the only reason and it is not wrong to do and not the only place
where we have it:

jthumshirn@glass:linux (master)$ git grep -A 1 "enum {" | grep "= 0" | wc -l
