Hi Justin,
Please use reverse xmas tree order - lognest line to shortest - for local
variables, even in cases of assignment such as this one.
In this case I would suggest splitting the declarations and assignment
of kdev. Something line this:
struct bcmasp_intf *intf = netdev_priv(dev);
int spb_index, nr_frags, ret, i, j;
unsigned int total_bytes, size;
struct bcmasp_tx_cb *txcb;
dma_addr_t mapping, valid;
struct bcmasp_desc *desc;
bool csum_hw = false;
struct device *kdev;
skb_frag_t *frag;
kdev = &intf->parent->pdev->dev;
...
