Subject: ata: pata_octeon_cf: Use correct byte order for DMA in when built little-endian.
X-Git-Tag: upstream/snapshot3+hdmi~6066^2~18
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1007c4bc0f66925d92886dd9e664a1d49bbf6140;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

ata: pata_octeon_cf: Use correct byte order for DMA in when built little-endian.

We need to set the 'endian' bit in this case.
