    sunqe: Fix compiler warnings · 266439c9
    Tushar Dave authored
    sunqe uses '__u32' for dma handle while invoking kernel DMA APIs,
    instead of using dma_addr_t. This hasn't caused any 'incompatible
    pointer type' warning on SPARC because until now dma_addr_t is of
    type u32. However, recent changes in SPARC ATU (iommu) enables 64bit
    DMA and therefore dma_addr_t becomes of type u64. This makes
    'incompatible pointer type' warnings inevitable.
    
    e.g.
    drivers/net/ethernet/sun/sunqe.c: In function ‘qec_ether_init’:
    drivers/net/ethernet/sun/sunqe.c:883: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type
    ./include/linux/dma-mapping.h:445: note: expected ‘dma_addr_t *’ but argument is of type ‘__u32 *’
    drivers/net/ethernet/sun/sunqe.c:885: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type
    ./include/linux/dma-mapping.h:445: note: expected ‘dma_addr_t *’ but argument is of type ‘__u32 *’
    
    This patch resolves above compiler warnings.
