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. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
