Message-ID: <20080223131555.GD4244@implementation> Date: Sat, 23 Feb 2008 14:15:55 +0100 From: Samuel Thibault <samuel.thibault@...-lyon.org> To: Andrew Morton <akpm@...ux-foundation.org>, linux-kernel@...r.kernel.org, Dmitry Torokhov <dtor@...l.ru>, Jiri Kosina <jkosina@...e.cz> Subject: [PATCH] Braille screen reader fixes Braille screen reader fixes: - console_cmdline's brl_options field is only required when braille console support is enabled. - Use strlcpy to copy the console name. - braille console support depends on VT support.
