From 3b4987bd33af91dd55325da395c236645b0aed16 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <ben@decadent.org.uk>

Subject: [PATCH] mips: Restore dma_cache_sync()
Commit 48e1fd5a81416a037f5a48120bf281102f2584e2 "MIPS: Convert DMA to
use dma-mapping-common.h" renamed and un-exported this function.
Since dma-mapping-common.h does not implement dma_cache_sync(), this
was incorrect.
