ASoC: cx20442: set tty->receiver_room in v253_open
Commit 79901317ce80 ("n_tty: Don't flush buffer when closing ldisc"), introduced in v3.10, revealed a bug in the cx20442 codec driver which has never been setting tty->receive_room on line discipline open as it should from the beginning. Fix it. Created and tested on Amstrad Delta against Linux-4.7-rc3 Signed-off-by: Janusz Krzysztofik <jmkrzyszt@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
