Message-id: <444432691808225221@wsc.cz> Date: Tue, 23 Jan 2007 15:42:24 +0100 (CET) From: Jiri Slaby <jirislaby@...il.com> To: Andrew Morton <akpm@...l.org> Cc: <osv@...ad.com> Subject: [PATCH 1/3] Char: mxser_new, do not null driver_data mxser_new, do not null driver_data driver_data are initialzed to NULL from tty layer, no need to do it in the driver. In this case it cases oops, since driver_data may be NULL for a short while for another closing process.
