ide: make ide_dma_timeout() available also for CONFIG_BLK_DEV_IDEDMA_SFF=n
Make ide_dma_timeout() available also for CONFIG_BLK_DEV_IDEDMA_SFF=n and convert {ics,au1xxx-}ide.c to use it. While at it: - dump ATA Status register content on error - use EXPORT_SYMBOL_GPL() to match the rest of SFF DMA functions Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
