  "message": "ide: mode limiting fixes for user requested speed changes\n\n* Add an extra argument to ide_max_dma_mode() for passing requested transfer\n  mode.  Use it as an upper limit when finding the best DMA for device/host.\n\n* Rename ide_max_dma_mode() to ide_find_dma_mode() and at the same time add\n  ide_max_dma_mode() wrapper which passes XFER_UDMA_6 as a requested mode to\n  ide_find_dma_mode().  Also add inline ide_find_dma_mode() version for\n  CONFIG_BLK_DEV_IDEDMA\u003dn case.\n\n* Pass requested transfer mode from ide_find_dma_mode() to ide_get_mode_mask()\n  to avoid false warning from eighty_ninty_three().\n\n* Use ide_find_dma_mode() to limit the user requested transfer mode in\n  ide_rate_filter().  Also limit the requested mode by host max PIO mode.\n\n\nAbove changes make ide_rate_filter() to:\n\n* Clip desired transfer mode down if it is invalid (values 0x0F, 0x13-0x19\n  and 0x25-0x39, values \u003e 0x46 were already clipped down, same for values\n  0x25-0x39 but iff UDMA was not supported by the host).\n\n* Clip desired transfer mode down if it is currently unsupported by IDE core\n  (PIO6 and MWDMA3-4, the latter were already clipped down but iff UDMA was\n  not supported by the host).\n\n* Clip desired transfer mode down according to the host capabilities\n  (UDMA modes were already clipped down but MWDMA/SWDMA/PIO weren\u0027t,\n  also -\u003eatapi_dma flag was not respected).\n\n* Clip desired transfer mode down according to the device capabilities\n  (except PIO modes for now which require mode work) - shouldn\u0027t be a\n  problem since ide_set_xfer_rate() is called _after_ device has accepted\n  given transfer mode.\n\nand also result in a number of host driver specific bugfixes:\n\n* icside\n  -

clip DMA modes down for ATAPI devices\n  - fix 0x00 being programmed as PIO timing for unsupported/invalid modes\n  - fix unsupported/invalid modes being set on the device\n\n* alim15x3\n  - clip DMA modes down for ATAPI devices (chipset revision \u003d\u003d 0x20 only)\n  -
