Subject: [PATCH 4/6] Char: mxser_new, don't check tty_unregister retval
Date: Sat, 7 Oct 2006 01:02:39 +0200 (CEST) [thread overview]
Message-ID: <34287982344@wsc.cz> (raw)
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.
