From: FUJITA Tomonori Date: Tue, 23 Jun 2009 01:48:37 +0000 (-0400) Subject: Blackfin: fix dma-mapping build errors X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=42b86e06c7db365f1947dda9b75317cbb3c9fb5b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git Blackfin: fix dma-mapping build errors The recent deprecation of dma_sync_{sg,single} ironically broke Blackfin systems. This is because we don't define dma_sync_sg_for_cpu at all, so until the DMA asm-generic conversion/cleanup is done after the next release, simply stub out the dma_sync_sg_for_{cpu,device} functions.
