Hi Greg,

After merging the usb tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/usb/serial/usb-serial.c: In function 'usb_serial_probe':
drivers/usb/serial/usb-serial.c:887:3: error: 'struct usb_serial_port' has no member named 'delta_msr_wait'

Caused by commit eba0e3c3a0ba ("USB: serial: fix hang when opening port")
fro the usb.current tree interacting with commit 53ab34dc50ad ("USB:
serial: remove unused MSR-wait queue") from the usb tree.

I have reverted the commit from usb.current on the assumption that the
problem it solves has been, or will be, solved some other way.
