Subject: rtc: rtc-davinci: return correct error code if rtc_device_register() fails
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9ed39bf931cbd95b30755dcb1ad724fe05565c3f;p=openwrt%2Fstaging%2Fblogic.git

rtc: rtc-davinci: return correct error code if rtc_device_register() fails

rtc_device_register() returns a pointer containing error code in case
of error.  Use that in the error return.
