+Subject: [PATCH 2/5] 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.
