Date: Mon, 14 Jan 2013 15:04:16 +1300 From: Tony Prisk <linux@...sktech.co.nz> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, vt8500-wm8505-linux-kernel@...glegroups.com, Tony Prisk <linux@...sktech.co.nz> Subject: [PATCH 1/4] serial: vt8500: Fix range-checking on vt8500_uart_ports Fix two instances where the index to vt8500_uart_ports is tested against > VT8500_MAX_PORTS. Correct usage should be >= VT8500_MAX_PORTS.
