From 2bbd57cad3d72334c9fcc4e229a5a5b04dc6aebc Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Mon, 13 Oct 2008 21:39:47 +0200 Subject: 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 --- drivers/ide/ide.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'drivers/ide/ide.c') diff --git a/drivers/ide/ide.c b/drivers/ide/ide.c index a498245dc213..083783e851d1 100644 --- a/drivers/ide/ide.c +++ b/drivers/ide/ide.c @@ -227,8 +227,7 @@ void ide_unregister(ide_hwif_t *hwif) kfree(hwif->sg_table); unregister_blkdev(hwif->major, hwif->name); - if (hwif->dma_base) - ide_release_dma_engine(hwif); + ide_release_dma_engine(hwif); mutex_unlock(&ide_cfg_mtx); } -- cgit v1.2.2
