ide: IDE_HFLAG_SERIALIZE_DMA bugfix
Patch re-ordering could be harmful: commit 1fd1890594bd355a4217f5658a34763e77decee3 Author: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> 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. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
