mm/hugetlb.c: fix duplicate variable
Adrian Bunk [Thu, 24 Jul 2008 04:27:03 +0000 (21:27 -0700)]
It's confusing that set_max_huge_pages() contained two different
variables named "ret", and although the code works correctly this should
be fixed.

The inner of the two variables can simply be removed.

Spotted by sparse.
