From 5d82720a7f41f0c877e026c7d17e3bf20ccdbae0 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Fri, 13 Mar 2009 21:16:13 +0100 Subject: ide: save the returned value of dma_map_sg dma_map_sg could return a value different to 'nents' argument of dma_map_sg so the ide stack needs to save it for the later usage (e.g. for_each_sg). The ide stack also needs to save the original sg_nents value for pci_unmap_sg.
