Subject: ixp4xx_hss: avoid calling dma_pool_create() with NULL dev
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3e2f61cd7a4e7642dcac4371734426e572f10370;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ixp4xx_hss: avoid calling dma_pool_create() with NULL dev

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