Subject: [PATCH 1/3] Char: mxser_new, do not null driver_data
Date: Tue, 23 Jan 2007 15:42:24 +0100 (CET)	[thread overview]
Message-ID: <444432691808225221@wsc.cz> (raw)

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.
