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.
|
