Subject: [PATCH 1/2] gpio: rcar: Fix error path for devm_kzalloc() failure

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".

Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>
Fixes: df0c6c80232f2ad4 ("gpio: rcar: Add minimal runtime PM support")
