From 4eaa3626a82149420d34b535dc673a2b6861da55 Mon Sep 17 00:00:00 2001 From: Chuanhong Guo Date: Thu, 13 Dec 2018 15:12:01 +0800 Subject: [PATCH] ath79: ag71xx: pass correct device pointer to dma functions linux 4.19 doesn't accept a NULL device for these functions. It also complains that the device struct in net_device doesn't have a dma_mask set. Pass the device struct from platform_device for these functions.
