So what you want is a function to pass to gpiochip_find() to match
the chip corresponding to a certain OF node. You have this:

static int tegra_get_gpiochip_from_of_node(struct gpio_chip *chip, void *data)
{
    return chip->of_node == data;
}

1) Rename this function tegra_gpiochip_match() as that is what it does.

2) Do something like:

static int tegra_gpiochip_match(struct gpio_chip *chip, void *data)
{
    return chip->fwnode == of_node_to_fwnode(data);
}

I think that should work?
