Subject: linux-next: build failure after merge of the final tree (tty tree
 related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/usb/serial/console.c: In function 'usb_console_setup':
drivers/usb/serial/console.c:168:16: error: invalid type argument of '->' (have 'struct ktermios')
drivers/usb/serial/console.c:169:4: error: incompatible type for argument 1 of 'tty_termios_encode_baud_rate'
include/linux/tty.h:449:13: note: expected 'struct ktermios *' but argument is of type 'struct ktermios'

Caused by commit adc8d746caa6 ("tty: move the termios object into the
tty").  Hopefully this is the last of them.

I have added the following fix patch for today:

Subject: [PATCH] tty: fix up usb serial console for termios change.

fixes these errors:

drivers/usb/serial/console.c: In function 'usb_console_setup':
drivers/usb/serial/console.c:168:16: error: invalid type argument of '->' (have 'struct ktermios')
drivers/usb/serial/console.c:169:4: error: incompatible type for argument 1 of 'tty_termios_encode_baud_rate'
