From 464069cae95f71ba670c7e3a90d919b18fb48d66 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 4 Sep 2014 17:31:35 +0530 Subject: [PATCH] power-supply: Avoid unnecessary 'goto' statements Using 'goto' statements for freeing resources on failures is a good choice as it makes code very clean, and reduces the chances of human errors. Though in most cases compiler may take care of this. But adding unnecessary 'goto' statements wouldn't make anything better. Code becomes less readable actually.
