sparc32: fix sparse warning in iommu.c
Fix following warning: iommu.c:69:21: warning: incorrect type in assignment (different address spaces) iommu_struct.regs is __iomem - fix up all users. Introduce sbus operations for all read/write operations. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
