3.5.7.13 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

commit 35623715818dfa720cccf99cd280dcbb4b78da23 upstream.

Fix to return -ENODEV in the chip not found error handling
case instead of 0, as done elsewhere in this function.
