Subject: [PATCH 02/14] tty: n_tty: use output character directly
Date:   Wed, 16 Aug 2023 12:58:08 +0200

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.
