From: FUJITA Tomonori Date: Mon, 10 Aug 2009 02:53:14 +0000 (+0900) Subject: sparc: Remove no-op dma_4v_sync_single_for_cpu and dma_4v_sync_sg_for_cpu X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=595cc8560783ea31ed1208dc1f97282a2a5606b7;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git sparc: Remove no-op dma_4v_sync_single_for_cpu and dma_4v_sync_sg_for_cpu Now sparc uses include/asm-generic/dma-mapping-common.h. pci_sun4v.c doesn't need to have no-op dma_4v_sync_single_for_cpu and dma_4v_sync_sg_for_cpu (dma-mapping-common.h does nothing if sync_{single|sg}_for_cpu hook is not defined). So we can remove them safely. Signed-off-by: FUJITA Tomonori Tested-by: Robert Reif Acked-by: David S.
