cs5530/sc1200: add PIO autotune fallback to ->ide_dma_check (3f019eea) · Commits · 戴 / test

* Add PIO autotune fallback to ->ide_dma_check. Since cs5530/sc1200 allow separate PIO and DMA timings, and cs5530/sc1200 always set ->autotune this change shouldn't have any other effect than bringing these drivers in-line with other host drivers wrt ->ide_dma_check implementations. * Fix ->ide_dma_check to return "-1" if DMA cannot be set. * Bump driver version.
