From 722d5e4ae89f061582cc46ccbbd3b5ae87a6e165 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Sat, 10 Feb 2007 01:45:22 -0800 Subject: [PATCH] [PATCH] Char: 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.
