   4 Subject: [PATCH 059/102] net: mediatek: use dma_addr_t correctly
   5
   6 dma_alloc_coherent() expects a dma_addr_t pointer as its argument,
   7 not an 'unsigned int', and gcc correctly warns about broken
   8 code in the mtk_init_fq_dma function:
   9
  10 drivers/net/ethernet/mediatek/mtk_eth_soc.c: In function 'mtk_init_fq_dma':
  11 drivers/net/ethernet/mediatek/mtk_eth_soc.c:463:13: error: passing argument 3 of 'dma_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]
  12
  13 This changes the type of the local variable to dma_addr_t.
