Subject: [PATCH 3.14 232/238] partitions: aix.c: off by one bug

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit d97a86c170b4e432f76db072a827fe30b4d6f659 upstream.

The lvip[] array has "state->limit" elements so the condition here
should be >= instead of >.

Fixes: 6ceea22bbbc8 ('partitions: add aix lvm partition support files')
