aha152x.c incompatible with scatterlist in 2.5.12

[Leo Liberti IrisTech]

Hello, I am having problems building kernel 2.5.12 on an i686 arch - in
particular the aha152x module (built as a PCMCIA module) does not compile
because it depends on "struct scatterlist" (see include/asm/scatterlist.h)
having the member "char* address". Kernels 2.4.x had

struct scatterlist {
    char *  address;    /* Location data is to be transferred to */
    char * alt_address; /* Location of actual if address is a
                         * dma indirect buffer.  NULL otherwise */
    unsigned int length;
};

whereas kernels 2.5.x have a different declaration of scatterlist:

struct scatterlist {
    struct page         *page;
    unsigned int        offset;
    dma_addr_t          dma_address;
    unsigned int        length;
};

I don't know enough about the SCSI subsystem changes to fix this myself -
does anyone have a hint?

Could you please reply also to [e-mail] as I am not
subscribed to the linux-kernel list.

Thanks,

Leo
