Input: aiptek - do not try to export associated event device
Do not try to export via sysfs associated event device - it does not work when evdev is a module that is loaded after aiptek; also it pokes too deply into input core internals. Userspace should rely on udev to set up permanent device name for the tablet. Signed-off-by: Rene van Paassen <rene.vanpaassen@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
