Wei Yongjun	9a4864c897	gpio: tb10x: fix return value check in tb10x_gpio_probe() ... In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Also remove the dev_err call to avoid redundant error message.
