Subject: [PATCH v2 3/8] serial: core: Use tty->index for port # in debug messages
Date: Sun, 10 Jan 2016 20:23:57 -0800 [thread overview]
Message-ID: <1452486242-7297-4-git-send-email-peter@hurleysoftware.com> (raw)
In-Reply-To: <1452486242-7297-1-git-send-email-peter@hurleysoftware.com>
The uart port may have already been removed by uart_remove_one_port();
use equivalent tty->index (which is always valid in these contexts)
instead.
