From 79491e53dcd73175473e3293a574f5e006b468be Mon Sep 17 00:00:00 2001 From: Eduardo Valentin Date: Wed, 17 Apr 2013 17:11:59 +0000 Subject: 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.
