Subject: thermal: Fix thermal_zone_of_sensor_register to match documentation
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=cd33dc9ac2977ebe30cecbf39d2992190fbac5b4;p=openwrt%2Fstaging%2Fblogic.git

thermal: Fix thermal_zone_of_sensor_register to match documentation

thermal_zone_of_sensor_register is documented as returning a pointer
to either a valid thermal_zone_device on success, or a corresponding
ERR_PTR() value.

In contrast, the function returns NULL when THERMAL_OF is configured
off. Fix this.
