From 96251a75e0097639a6df558e4e62f762100f03d3 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 25 Feb 2021 17:21:34 -0800 Subject: [PATCH] lib/cmdline: remove an unneeded local variable in next_arg() The local variable 'next' is unneeded because you can simply advance the existing pointer 'args'.
