From: Wei Yongjun <yongjun_...@trendmicro.com.cn>
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 there is already a error message within
devm_ioremap_resource(), so remove the dev_err call to avoid redundant
error message.
