Subject: tty: n_tty: use output character directly
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=d414034ec901c3821f17bd44b8eaaa5820253417;p=linux.git

tty: n_tty: use output character directly

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.
