Subject: make sba DMA mapping functions static
X-Git-Tag: upstream/snapshot3+hdmi~19877^2~31
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=055bcf99a1471ff0a2ef24863098f946a09c9161;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

make sba DMA mapping functions static

Now we don't need to export these DMA mapping functions.
