Subject: thermal: exynos_thermal: return a proper error code while thermal_zone_device_registe... 
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=043e4652bf3378883e7c0db38fa47fa8e2558f9c;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

thermal: exynos_thermal: return a proper error code while thermal_zone_device_register fail.

we are returning EINVAL while the thermal_zone_device_register function fail.
instead we can use the return value from the thermal_zone_device_register by
using PTR_ERR.
