Subject: [039/200] USB: tty: fix incorrect use of tty_insert_flip_string_fixed_flag

2.6.34-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johan Hovold <jhovold@...il.com>

commit 70ced221cc9f041481f129e63cc5b1dedb0ff959 upstream.

Fix regression introduced by commit
a108bfcb372d8c4452701039308fb95747911c59 (USB: tty: Prune uses of
tty_request_room in the USB layer) which broke three drivers
(cypress_m8, digi_acceleport and spcp8x5) through incorrect use of
tty_insert_flip_string_fixed_flag.
