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

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

From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>

commit 35623715818dfa720cccf99cd280dcbb4b78da23 upstream.

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