gpio: pxa: Fix return value of pxa_gpio_probe()
When call function devm_platform_ioremap_resource(), we should use IS_ERR() to check the return value and return PTR_ERR() if failed. Fixes: 542c25b7a209 ("drivers: gpio: pxa: use devm_platform_ioremap_resource()") Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>
