Subject: [patch 097/118] lib/cmdline: remove an unneeded local variable in next_arg()
Date: Thu, 25 Feb 2021 17:21:34 -0800 [thread overview]
Message-ID: <20210226012134.dlagKsZvQ%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210225171452.713967e96554bb6a53e44a19@linux-foundation.org>
From: Masahiro Yamada <masahiroy@kernel.org>
Subject: 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'.
