[RFC/PATCH v2 1/2] gpio-rcar: Make the platform data gpio_base field signed

[Laurent Pinchart]

The gpio_base field is used to specify the desired GPIO base for the
GPIO controller. The GPIO core can automatically allocate a GPIO number
range when the base is set to -1. To make this possible, make the field
signed.
