- Subject: [PATCH 060/102] 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.
