  "message": "atiixp/jmicron/triflex: fix PIO fallback\n\n* atiixp: if DMA can\u0027t be used atiixp_config_drive_for_dma() should return 0,\n  atiixp_dma_check() will tune the correct PIO mode anyway\n\n* jmicron: if DMA can\u0027t be used config_chipset_for_dma() should return 0,\n  micron_config_drive_for_dma() will tune the correct PIO mode anyway\n\n  config_jmicron_chipset_for_pio(drive, !speed) doesn\u0027t program\n  device transfer mode for speed !\u003d 0 (only wastes some CPU cycles\n  on ide_get_best_pio_mode() call) so remove it\n\n* triflex: if DMA can\u0027t be used triflex_config_drive_for_dma() should return 0,\n  triflex_config_drive_xfer_rate() will tune correct PIO mode anyway\n\nAbove changes also fix (theoretical) issue when -\u003espeedproc fails to set\ndevice transfer mode (i.e. when ide_config_drive_speed() fails to program it)\nbut one of DMA transfer modes is already enabled on the device by the BIOS.\nIn such scenario ide_dma_enable() will incorrectly return true statement\nand -\u003eide_dma_check will try to enable DMA on the device.\n\nSigned-off-by: Bartlomiej Zolnierkiewicz \u003cbzolnier@gmail.com\u003e\n\n",
