thermal: cpu_cooling: standardize end of function
Just for code readiness, this patch makes all functions on this file to have a blank line before their returns. Now, some functions follow this pattern, and others will not have a blank line. So, this patch makes it a single pattern. Signed-off-by: Eduardo Valentin <eduardo.valentin@ti.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
