[PATCH] make __ide_dma_off() generic and remove ide_hwif_t->ide_dma_off

From: Bartlomiej Zolnierkiewicz <hidden>
Date: 2004-02-09 14:50:00
Also in: lkml

Incremental to "[PATCH] remove __ide_dma_count() and ide_hwif_t->ide_dma_count".

Move ide-dma.c:__ide_dma_off() outside of #ifdef CONFIG_BLK_DEV_IDEDMA_PCI,
so it can be used for all DMA capable hosts.  Remove ide_hwif_t->ide_dma_off.
