ide: add struct ide_dma_ops (take 3)
Add struct ide_dma_ops and convert core code + drivers to use it. While at it: * Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods. * Drop "ide_" "infixes" from DMA methods. * au1xxx-ide.c: - use auide_dma_{test_irq,end}() directly in auide_dma_timeout() * pdc202xx_old.c: - drop "old_" "infixes" from DMA methods * siimage.c: - add siimage_dma_test_irq() helper - print SATA warning in siimage_init_one() * Remove no longer needed ->init_hwif implementations. v2: * Changes based on review from Sergei: - s/siimage_ide_dma_test_irq/siimage_dma_test_irq/ - s/drive->hwif/hwif/ in idefloppy_pc_intr(). - fix patch description w.r.t. au1xxx-ide changes - fix au1xxx-ide build - fix naming for cmd64*_dma_ops - drop "ide_" and "old_" infixes - s/hpt3xxx_dma_ops/hpt37x_dma_ops/ - s/hpt370x_dma_ops/hpt370_dma_ops/ - use correct DMA ops for HPT302/N, HPT371/N and HPT374 - s/it821x_smart_dma_ops/it821x_pass_through_dma_ops/ v3: * Two bugs slipped in v2 (noticed by Sergei): - use correct DMA ops for HPT374 (for real this time) - handle HPT370/HPT370A properly Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
