    [ARM] omap: Fix IO_ADDRESS() macros · e8a91c95
    Russell King authored
    OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies
    for use with __raw_{read|write}* for accessing registers.  Therefore,
    these macros should return (void __iomem *) cookies, not integer values.
    
    Doing this improves typechecking, and means we can find those places
    where, eg, DMA controllers are incorrectly given virtual addresses to
    DMA to, or physical addresses are thrown through a virtual to physical
    address translation.
