From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>
It maybe call devm_ioremap to map device IO address to memory. When
devm_ioremap operation failed, we should return '-ENOMEM' instead of
'-EINVAL' to alert callers in this case, callers may have different
operation later. Moreover, '-EINVAL' will be confused with the
previous error code when getting resource failed.
