Subject: linux-next: manual merge of the ttydev tree with the usb.current
 tree

Hi Alan,

Today's linux-next merge of the ttydev tree got a conflict in
drivers/usb/serial/usb-serial.c between commit
a00b8d98aca97bfb6fa983f41dae25b424058592 ("USB: fix usage count in usb
serial generic open regarding autoresume") from the usb.current tree and
commit 73fed8403623653560cc2f35c9b62891adaf6b4b
("tty-usb-error-unlock-fix") from the ttydev tree.

Just context changes.  I have fixed it up (see below) and can carry the
fix as necessary.
