ata: libata-transport: fix {dma|pio|xfer}_mode sysfs filesThe {dma|pio}_mode sysfs files are incorrectly documented as having alist of the supported DMA/PIO transfer modes, while the correspondingfields of the *struct* ata_device hold the transfer mode IDs, not masks.To match these docs, the {dma|pio}_mode (and even xfer_mode!) sysfsfiles are handled by the ata_bitfield_name_match() macro which leads toreading such kind of nonsense from them:$ cat /sys/class/ata_device/dev3.0/pio_modeXFER_UDMA_7, XFER_UDMA_6, XFER_UDMA_5, XFER_UDMA_4, XFER_MW_DMA_4,XFER_PIO_6, XFER_PIO_5, XFER_PIO_4, XFER_PIO_3, XFER_PIO_2, XFER_PIO_1,XFER_PIO_0Using the correct ata_bitfield_name_search() macro fixes that:$ cat /sys/class/ata_device/dev3.0/pio_modeXFER_PIO_4While fixing the file documentation, somewhat reword the {dma|pio}_modefile doc and add a note about being mostly useful for PATA devices tothe xfer_mode file doc...Fixes: d9027470b886 ("[libata] Add ATA transport class")Signed-off-by: Sergey Shtylyov Cc: stable@vger.kernel.orgSigned-off-by: Damien Le Moal List of files: /linux-6.15/Documentation/ABI/testing/sysfs-ata
