ide: switch to DMA-mapping API part #2
Follow-up to commit 5c05ff68b9a9b40a9be949497e0aa980185565cf ("ide: switch to DMA-mapping API"): * pci_{alloc,free}_consistent() -> dma_{alloc,free}_coherent() in ide_{allocate,release}_dma_engine(). * Add ->prd_max_nents and ->prd_ent_size fields to ide_hwif_t (+ set default values in ide_allocate_dma_engine()). * Make ide_{allocate,release}_dma_engine() available also for CONFIG_BLK_DEV_IDEDMA_SFF=n. Then convert au1xxx-ide.c, scc_pata.c and sgiioc4.c to use them. * Add missing ->init_dma method to scc_pata. This patch also fixes: - ->dmatable_cpu leak for au1xxx-ide - too early realease of ->dmatable_cpu for scc_pata - wrong amount of ->dmatable_cpu memory being freed for sgiioc4 While at it: - remove superfluous ->dma_base check from ide_unregister() - return -ENOMEM on error in ide_release_dma_engine() - beautify error message in ide_release_dma_engine() Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
