From f67ae98352284d7ac1e03f3a872e33c68ea35a5b Mon Sep 17 00:00:00 2001 From: David Daney Date: Fri, 17 Oct 2008 17:48:53 -0700 Subject: MIPS: Don't unmap the memory for dma_sync*. We were getting away with this for so long only because the only platform with a non-empty plat_unmap_dma_mem() doesn't call dma_sync_sg_for_cpu() and dma_sync_sg_for_device() from its commonly used drivers.
