[PATCH 1/3] net: mediatek: use dma_addr_t correctly

From: Arnd Bergmann <hidden>
Date: 2016-03-14 14:08:03
Also in: linux-arm-kernel, linux-mediatek, lkml
Subsystem: mediatek ethernet driver, networking drivers, the rest · Maintainers: Felix Fietkau, Lorenzo Bianconi, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

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.
