   4 Subject: [PATCH 060/102] net: mediatek: remove incorrect dma_mask assignment
   5
   6 Device drivers should not mess with the DMA mask directly,
   7 but instead call dma_set_mask() etc if needed.
   8
   9 In case of the mtk_eth_soc driver, the mask already gets set
  10 correctly when the device is created, and setting it again
  11 is against the documented API.
  12
  13 This removes the incorrect setting.
