Date: Tue, 7 Aug 2012 21:47:40 +0200 From: Jiri Slaby <jslaby@...e.cz> To: gregkh@...uxfoundation.org Cc: alan@...ux.intel.com, linux-kernel@...r.kernel.org, jirislaby@...il.com, Samo Pogacnik <samo_pogacnik@....net> Subject: [PATCH 15/41] TTY: ttyprintk, initialize tty_port earlier After tty_register_driver is called, it is too late to initialize a guy with which we operate in open. When a process already called open(2) on that node, the structures may be in use uninitialized. Move the initialization prior to tty_register_driver.
