4.2.8-ckt1 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Dan Carpenter <dan.carpen...@oracle.com> commit 1f35d04a02a652f14566f875aef3a6f2af4cb77b upstream. The iomap[] array has PCIM_IOMAP_MAX (6) elements and not DEVICE_COUNT_RESOURCE (16). This bug was found using a static checker. It may be that the "if (!(mask & (1 << i)))" check means we never actually go past the end of the array in real life.
