3.4.113-rc1 review patch. If anyone has any objections, please let me know.
------------------
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.
Fixes: ec04b075843d ('iomap: implement pcim_iounmap_regions()')
