Use the netdevice struct device .parent field when calling dma_pool_create(): the .dma_coherent_mask and .dma_mask pertains to the bus device on the hardware (platform) bus in this case, not the struct device inside the network device. This makes the pool allocation work. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> --- drivers/net/ethernet/xscale/ixp4xx_eth.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) -- 2.21.0
