mm/mmap.c: __vma_adjust(): suppress uninitialized var warning
The code is OK, but it fools gcc. mm/mmap.c:802 __vma_adjust() error: uninitialized symbol 'next_next'. Fixes: 524e00b36e8c5 ("mm: remove rb tree.") Reported-by: kernel test robot <lkp@intel.com> Cc: Liam R. Howlett <Liam.Howlett@Oracle.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
