Hi Linus, Alexandre,
This patch series converts the Renesas R-Car Gen2 GPIO driver to use the
gpiolib irqchip helpers.
It was tested on r8a7791/koelsch.
Thanks!

If the call to devm_kzalloc() fails, nothing must be cleant up.
This was missed before because gpio_rcar_probe() had a "return"
statement after the first "goto err0".

Switch the R-Car Gen2 GPIO driver to use the gpiolib irqchip helpers.
While doing this also make sure that gpiochip_irqchip_add() is called
after the gpiochip itself is registered, as required.
