    Subject[ 082/102] drivers/rtc/rtc-pcf2123.c: fix error return code in pcf2123_probe()
    Date
    3.9-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.
