X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=82b12e232d2a71f566dca48df4ae4548e6d8d53d;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git FRV: move DMA macros to scatterlist.h for consistency. To be consistent with other architectures, these two DMA macros should be defined in scatterlist.h as opposed to dma-mapping.h Signed-off-by: Robert P. J.
