This causes kernel oops when user tries to look up (or change) current keymap. While the proper fix would be to make remotes handle keymap changes we'll just remove keycodemax and keycodesize initialization so EVIOCGKEYCODE and EVIOCSKEYCODE will simply return -EINVAL. http://bugzilla.kernel.org/show_bug.cgi?id=8312 Signed-off-by: olaf.kirch@oracle.com Signed-off-by: Dmitry Torokhov Signed-off-by: Linus Torvalds --- diff --git a/drivers/media/dvb/dvb-usb/dvb-usb-remote.c b/drivers/media/dvb/dvb-usb/dvb-usb-remote.c index 9511a31c8f50..68ed3a788083 100644 --- a/drivers/media/dvb/dvb-usb/dvb-usb-remote.c +++ b/drivers/media/dvb/dvb-usb/dvb-usb-remote.c @@ -107,8 +107,6 @@ int dvb_usb_remote_init(struct dvb_usb_device *d) return -ENOMEM; input_dev->evbit[0] = BIT(EV_KEY); - input_dev->keycodesize = sizeof(unsigned char); - input_dev->keycodemax = KEY_MAX; input_dev->name = "IR-receiver inside an USB DVB receiver"; input_dev->phys = d->rc_phys; usb_to_input_id(d->udev, &input_dev->id);
