Subject: powerpc/pci: Default to dma_direct_ops for pci dma_ops
X-Git-Tag: firefly_0821_release~15194^2~17
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=32ac57668dccf6c4ad5522b61a86fe211886c180;p=firefly-linux-kernel-4.4.55.git

powerpc/pci: Default to dma_direct_ops for pci dma_ops

This will allow us to remove the ppc32 specific checks in get_dma_ops()
that defaults to dma_direct_ops if the archdata is NULL.  We really
should always have archdata set to something going forward.
