Subject: [PATCH 1/4 v3] serial: vt8500: Fix range-checking on vt8500_uart_ports
Date: Thu, 17 Jan 2013 08:05:40 +1300 [thread overview]
Message-ID: <1358363143-7154-2-git-send-email-linux@prisktech.co.nz> (raw)
In-Reply-To: <1358363143-7154-1-git-send-email-linux@prisktech.co.nz>
Fix two instances where the index to vt8500_uart_ports is tested
against > VT8500_MAX_PORTS. Correct usage should be >= VT8500_MAX_PORTS.
