+Subject: [PATCH 68/91] net: mediatek: remove incorrect dma_mask assignment
+
+Device drivers should not mess with the DMA mask directly,
+but instead call dma_set_mask() etc if needed.
+
+In case of the mtk_eth_soc driver, the mask already gets set
+correctly when the device is created, and setting it again
+is against the documented API.
+
+This removes the incorrect setting.
