From ead568c9cdab2592abdbd1f023931665cc24b5db Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Fri, 8 Dec 2006 02:38:26 -0800 Subject: [PATCH] [PATCH] Char: mxser_new, don't check tty_unregister retval Like other drivers silently unregister_tty_driver and put_tty_driver. It shouldn't be busy when module release function is called, since we are not bsd, no refs shouldn't be held.
