pinctrl: amd: fix error return code in amd_gpio_probe()
platform_get_irq() returns an error code, but the pinctrl-amd driver ignores it and always returns -EINVAL. This is not correct and, prevents -EPROBE_DEFER from being propagated properly. Print and propagate the return value of platform_get_irq on failure. This issue was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R.
