    pnp: only assign IORESOURCE_DMA if CONFIG_ISA_DMA_API is enabled · 586f83e2
    David Rientjes authored
    IORESOURCE_DMA cannot be assigned without utilizing the interface
    provided by CONFIG_ISA_DMA_API, specifically request_dma() and
    free_dma().  Thus, there's a strict dependency on the config option and
    limits IORESOURCE_DMA only to architectures that support ISA-style DMA.
    
    ia64 is not one of those architectures, so pnp_check_dma() no longer
    needs to be special-cased for that architecture.
    
    pnp_assign_resources() will now return -EINVAL if IORESOURCE_DMA is
    attempted on such a kernel.
