TTY: open/release, cleanup printks
* use __func__ instead of hardcoded names (tty_release_dev is a non-existant function) * add missing \n's * unwrap for better grepping Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
