From 1a2bd6b257592cc05e9dd3d36e5810466a075fc3 Mon Sep 17 00:00:00 2001 From: Mark Einon Date: Fri, 16 Nov 2012 10:47:38 +0000 Subject: [PATCH] staging: et131x: Remove alignment offset padding on DMA buffer allocation/free This padding was used to align buffers to a 4k boundary when returned from dma_alloc_coherent(). As the buffers are already 4k aligned, and the alignment no longer performed, the padding is not needed.
