We don't need to export them since they're not being used outside the
file. The next time I try to find the callers for these things I will
know I won't need to look outside intel_ddi.c.

You don't do cscope/ctags/whatever?

But anyway static is good since it hands the compiler a bit more rope.

When a function is static I just put the vim cursor on top of its name
and press * and go with n/N. I think that's always faster than any
other method. But yeah, for non-static stuff I end up having to use
better tools.
