From a0b68486f6f680c7c0352a47c60042d7d95ffd87 Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Thu, 7 Jul 2016 19:08:54 -0400 Subject: [PATCH] net: ethernet: bgmac: add dma_dev pointer The dma buffer allocation, etc references a dma_dev device pointer from the bcma core. In anticipation of removing the bcma requirement for this driver, these must be changed to not reference that struct. Add a dma_dev device pointer to the bgmac stuct and reference that instead.
