From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>
In many of the error handling case, the return value 'ret' not set and 0 will be return from d40_probe() even if error, but we should return a negative error code instead in those error handling case. This patch fixed them, and also removed useless variable 'err'.
