sparc: _sparc_find_resource() should check for exact matches
The address that's passed to _sparc_find_resource() should always be the start address of a resource: - iounmap() passes a page-aligned virtual address, while the original address was created by adding the in-page offset to the resource's start address, - sbus_free_coherent() and pci32_free_coherent() should be passed an address obtained from sbus_alloc_coherent() resp. pci32_alloc_coherent(), which is always a resource's start address. Hence replace the range check by a check for an exact match. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Acked-by: David S. Miller <davem@davemloft.net>
