We have added polled mode to the normal input devices with the intent of retiring input_polled_dev. This converts clps711x-keypad driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV. Also use managed API when allocating input device, this allows us to remove clps711x_keypad_remove() method.
