I didn't get why this was necessary...
* Convert cy82c693_dma_enable() to become cy82c693_set_dma_mode()
and remove no longer needed cy82c693_ide_dma_on(). Then set
IDE_HFLAG_CY82C693 instead of IDE_HFLAG_TRUST_BIOS_FOR_DMA in
cy82c693_chipset.
* Bump driver version.
As a result of this patch cy82c693 driver will configure and use DMA on
all SWDMA0-2 and MWDMA0-2 capable ATA devices instead of relying on BIOS.

Useless intializers for 'index' and 'data'.
