usb serial: more fixes and groundwork for tty changes
- If a termios change fails due to lack of memory we should copy the old settings back over as the device has not changed - Note various locking problems - kl5kusb105 had various remaining tty flag handling problems - Make safe_serial use tty_insert_flip_string not open coded loops - set termios speed properly in usb_serial Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
