Input: polldev - immediately poll device upon opening
To allow open/ioctl(EVIOCGABS)/close use pattern for polled devices read the device in context of open() call instead of offloading the first read to a workqueue. This will ensure that once call to open() returns device would have cached reasonably recent axis values that can be retrieved via appropriate ioctl. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
