Subject: [ 2/3] hwmon: fix error return code in abituguru_probe()

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

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

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

commit ecacb0b17c08fae89f65468727f0e4b8e91da4e1 upstream.

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.
