Subject: linux-next: build failure after merge of the tty tree

Hi Greg,

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

drivers/staging/dgrp/dgrp_net_ops.c: In function 'dgrp_input':
drivers/staging/dgrp/dgrp_net_ops.c:216:27: error: 'struct tty_struct' has no member named 'real_raw'
drivers/staging/dgrp/dgrp_net_ops.c:229:8: error: 'struct tty_struct' has no member named 'read_cnt'
drivers/staging/dgrp/dgrp_net_ops.c:229:8: error: 'struct tty_struct' has no member named 'read_cnt'
drivers/staging/dgrp/dgrp_net_ops.c:261:30: error: 'struct tty_struct' has no member named 'real_raw'
drivers/staging/dgrp/dgrp_net_ops.c:276:28: error: 'struct tty_struct' has no member named 'real_raw'

Caused by commits 53c5ee2cfb4d ("TTY: move ldisc data from tty_struct:
simple members") and ba2e68ac6157 ("TTY: move ldisc data from tty_struct:
read_* and echo_* and canon_* stuff") interacting with commit
0b52b7497271 ("staging: Add dgrp driver for Digi Realport devices") now
in Linus' tree.

I disabled building of the dgrp driver for now using this merge fix patch:
