From e45d0fad4a5f8c2d69084dbda98635adcd3f8478 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sun, 12 Jan 2020 13:04:50 +0100 Subject: [PATCH] net: ethernet: ixp4xx: Use parent dev for DMA pool 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.
