This is a question that I often run into, when I want to keep this order,
i.e. lines longest to shortest, but the line of the pointer which get later
is longer. For this example:
struct wx *wx = txgbe->wx;
struct device *dev = &wx->pdev->dev;
should I split the line, or put the long line abruptly there?

I can access this GPIO region directly, do I really need to use regmap?
