Subject: [PATCH v2 05/14] tty: n_tty: make n_tty_data::num_overrun unsigned
Date: Sun, 27 Aug 2023 09:41:38 +0200	[thread overview]
Message-ID: <20230827074147.2287-6-jirislaby@kernel.org> (raw)
In-Reply-To: <20230827074147.2287-1-jirislaby@kernel.org>

n_tty_data::num_overrun is unlikely to overflow in a second. But make it
explicitly unsigned to avoid printing negative values.
