Thanks for these. Unfortunately you didn't cc me on the individual patches so I had to go and look in the online archive. Comments below.

I don't think this is a good fix. It fixes the error, but it doesn't
fix the code.
phy_ring_head and phy_ring_tail are conceptually the same type, so they
should both be dma_addr_t.

I don't really like
ring->rx_dma = dma_alloc_coherent(eth->dev,
- ring->rx_ring_size * sizeof(*ring->rx_dma),
- &ring->rx_phys,
- GFP_ATOMIC | __GFP_ZERO);
+ ring->rx_ring_size *
+ sizeof(*ring->rx_dma),
+ &ring->rx_phys,
+ GFP_ATOMIC | __GFP_ZERO);
as you need to look at the end of the lines to see that some end ',' and
one ends '*'.
One solution would be to make it
ring->rx_dma = dma_alloc_coherent(eth->dev,
(ring->rx_ring_size *
sizeof(*ring->rx_dma)),
&ring->rx_phys,
GFP_ATOMIC | __GFP_ZERO);
i.e. use parentheses around the multiplication so that the
second line gets indented a bit.
I would also be happy with
ring->rx_dma = dma_alloc_coherent(
eth->dev,
ring->rx_ring_size * sizeof(*ring->rx_dma),
&ring->rx_phys,
GFP_ATOMIC | __GFP_ZERO);
If there is nothing after the open '(', then the alignment rules are
different (I think).
Note that whatever change you make in mtk_dma_rx_alloc() is also
required in mtk_pdma_tx_alloc().
Thanks,
