Use a flexible array member to combine kzalloc and kcalloc.

 struct msc313_gpio {
        void __iomem *base;
        const struct msc313_gpio_data *gpio_data;

Do you wanna add:

const unsigned int saved_size;

So in the code there's

for (i = 0; i < gpio->gpio_data->num; i++)

which is equivalent to match->num.

__counted_by doesn't support pointers AFAIK.

This is a regular flexible array of u8. It should work fine with
__counted_by and I too am in favor of using it as it has become
standard for flexible arrays.

That requires adding an extra variable in the struct.
