ide: pass command to ide_map_sg()
* Set IDE_TFLAG_WRITE flag and ->rq also for ATA_CMD_PACKET commands. * Pass command to ->dma_setup method and update all its implementations accordingly. * Pass command instead of request to ide_build_sglist(), *_build_dmatable() and ide_map_sg(). While at it: * Fix scc_dma_setup() documentation + use ATA_DMA_WR define. * Rename sgiioc4_build_dma_table() to sgiioc4_build_dmatable(), change return value type to 'int' and drop unused 'ddir' argument. * Do some minor cleanups in [tx4939]ide_dma_setup(). There should be no functional changes caused by this patch. Acked-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
