DVB: dvb-usb-remote - fix oops when changing keymap
DVB USB remotes do not support changing keycode maps but set input_dev->keycodesize and input_dev->keycodemax without setting input_dev->keycode. 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 <dtor@mail.ru> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
