This isn't actually the original purpose of CONFIG_GENERIC_ISA_DMA (it
was to allow an architecture to provide ISA-like DMA without having to
use the ISA DMA request/free functions - eg, they need to claim interrupts
on request_dma() and free them on free_dma()).

However, since this function isn't used on ARM, it doesn't affect me,
and so I don't have any problem with this patch. 8)
