Subject: [PATCH 02/14] tty: n_tty: use output character directly
Date: Wed, 16 Aug 2023 12:58:08 +0200 [thread overview]
Message-ID: <20230816105822.3685-5-jirislaby@kernel.org> (raw)
In-Reply-To: <20230816105822.3685-1-jirislaby@kernel.org>
There is no point to use a local variable to store the character when we
can pass it directly. This assignment comes from era when we used to do
get_user(c, b). We no longer need this, so fix this.
