From 38e12f64a165e83617c21dae3c15972fd8d639f5 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Tue, 8 Sep 2009 12:00:46 -0700 Subject: [PATCH] ioat1: kill unused unmap parameters The unified ioat1/ioat2 ioat_dma_unmap() implementation derives the source and dest addresses from the unmap descriptor. There is no longer a need to track this information in struct ioat_desc_sw.
