Subject: [PATCH 1/3] net: mediatek: use dma_addr_t correctly
Date: Mon, 14 Mar 2016 15:07:10 +0100 [thread overview]
Message-ID: <1457964435-2945038-1-git-send-email-arnd@arndb.de> (raw)
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.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
