From 35e82b2926537c0e7264f84b38045b522fa82003 Mon Sep 17 00:00:00 2001 From: Sami Kerola Date: Mon, 29 May 2017 18:39:22 +0100 Subject: lib: simplify cpuset if clauses that return There is no need for 'else' when 'if' will return. In same go move call of tolower() to last possible moment in char_to_val(), a lot of time hex values should hit 0-9 range, and it can be omitted.
