POWERPC: Set dma_data correctly for direct_ops on pasemi
More late-caught fallout from the mainline merge. Commit 35e4a6e26d0c6bc7f32087db61f0fb3666531183 ("[POWERPC] Use archdata.dma_data in dma_direct_ops and add the offset") claimed "Now that all platforms using dma_direct_offset setup the archdata.dma_data correctly, ..." ..but nope -- the pasemi iommu setup code that disables translation on the DMA pci device didn't set dma_data correctly. This fixes it. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
