From 039956e9199b71ea673954e025f52f319110ca58 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Wed, 10 Mar 2010 15:23:15 -0800 Subject: Documentation/DMA-API.txt: remove deprecated function descriptions dma_sync_single(), pci_dma_sync_single(), dma_sync_sg(), and pci_dma_sync_sg() are deprecated. We should not advertise them. Signed-off-by: FUJITA Tomonori Acked-by: David S.
