Subject: hwmon: (nct6775) Use return value from find_temp_source
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e8ab508c27be9868411b6578507e93e02bdb8cdb;p=openwrt%2Fstaging%2Fblogic.git

hwmon: (nct6775) Use return value from find_temp_source

smatch complains that we don't use the return value from find_temp_source().
Valid point, only find_temp_source() doesn't return a valid error code.
Have it return a valid error code and use it.
