[PATCH 04/26] Input: maplemouse - stop polling and clear callback on close

[Dmitry Torokhov]

In dc_mouse_close(), pass NULL instead of dc_mouse_callback to
maple_getcond_callback() to both stop polling and clear the callback
pointer when the input device is closed.

This makes the manual clearing of mdev->callback in
remove_maple_mouse() redundant, as input_unregister_device()
automatically closes the device if it was open. Remove the redundant
assignment.
