gpio: sifive: add missing check for platform_get_irq
Add the missing check for platform_get_irq() and return error code if it fails. The returned error code will be dealed with in builtin_platform_driver(sifive_gpio_driver) and the driver will not be registered. Fixes: f52d6d8b43e5 ("gpio: sifive: To get gpio irq offset from device tree data") Signed-off-by: Jiasheng Jiang <jiasheng@iscas.ac.cn> Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
