    ide: add ide_set_dma() helper (v2) · 3608b5d7
    Bartlomiej Zolnierkiewicz authored
    * add ide_set_dma() helper and make ide_hwif_t.ide_dma_check return
      -1 when DMA needs to be disabled (== need to call ->ide_dma_off_quietly)
       0 when DMA needs to be enabled  (== need to call ->ide_dma_on)
       1 when DMA setting shouldn't be changed
    * fix IDE code to use ide_set_dma() instead if using ->ide_dma_check directly
    
    v2:
    * updated for scc_pata
