Subject: [PATCH 06/22] Input: clps711x-keypad - switch to using polled mode of input devices
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.
