From 1024c5f4be4fc5b00337464fb8a442bebf15df68 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sun, 4 May 2008 17:03:41 +0200 Subject: [PATCH] ide: IDE_HFLAG_SERIALIZE_DMA bugfix Patch re-ordering could be harmful: commit 1fd1890594bd355a4217f5658a34763e77decee3 Author: Bartlomiej Zolnierkiewicz Date: Sat Apr 26 22:25:24 2008 +0200 ide: add IDE_HFLAG_SERIALIZE_DMA host flag ... is buggy because ->init_dma method / ide_hwif_setup_dma() is called before IDE_HFLAG_SERIALIZE_DMA host flag is checked. Fix it by checking IDE_HFLAG_SERIALIZE[_DMA] after DMA initialization.
