From 145106e81090fcdfb57b7f2e90b98c6445b6f33d Mon Sep 17 00:00:00 2001 From: Muli Ben-Yehuda Date: Tue, 26 Sep 2006 10:52:32 +0200 Subject: [PATCH] [PATCH] remove superflous BUG_ON's in nommu and gart There's no need to check for invalid DMA data direction in nommu and gart since we do it in dma-mapping.h anyway before calling the individual dma-ops.
