Hi Folks,

If you try to disable IDE DMA from Kconfig, you'll end up with an
undefined symbol, ide_hwif_setup_dma().

The attached rather ugly patch fixes the problem by defining a
dummy function.

If you disable IDE_DMA, then the other chipset drivers cannot be
enabled --- the config system won't let you.
With IDE_DMA disabled and all chipsets disabled, I see:

drivers/built-in.o(.text+0x9f8bc): In function `ide_hwif_setup_dma':
: undefined reference to `ide_setup_dma'

And *that's* what my patch was supposed to fix.
