Subject: ixp4xx_eth: avoid calling dma_pool_create() with NULL dev
X-Git-Tag: v3.7-rc7~22^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1a4901177574083c35fafc24c4d151c2a7c7647c;p=platform%2Fkernel%2Flinux-exynos.git

ixp4xx_eth: avoid calling dma_pool_create() with NULL dev

Use &port->netdev->dev instead of NULL since dma_pool_create() doesn't
allow NULL dev.
