Subject: [PATCH 1/2] [media] mantis: Move jump label to activate dead code
Date: Sun, 15 Feb 2015 13:11:04 +0100 [thread overview]
Message-ID: <1424002265-16865-2-git-send-email-s.jegen@gmail.com> (raw)
In-Reply-To: <1424002265-16865-1-git-send-email-s.jegen@gmail.com>
Due to a misplaced goto label mantis_uart_exit is never called. Adjusting
the label position (while correcting its numbering) changes this.
This issue was found using the smatch static checker.
