- Subject: [PATCH 62/81] net: mediatek: use dma_addr_t correctly
- dma_alloc_coherent() expects a dma_addr_t pointer as its argument,
- not an 'unsigned int', and gcc correctly warns about broken
- code in the mtk_init_fq_dma function:
- drivers/net/ethernet/mediatek/mtk_eth_soc.c: In function 'mtk_init_fq_dma':
- 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]
- This changes the type of the local variable to dma_addr_t.
