[PATCH 07/22] Input: jornada680_kbd - switch to using polled mode of input devices

From: Dmitry Torokhov
Date: Thu Oct 17 2019 - 16:42:49 EST


We have added polled mode to the normal input devices with the intent of
retiring input_polled_dev. This converts jornada680_kbd driver to use the
polling mode of standard input devices and removes dependency on
INPUT_POLLDEV.

Say Y here if you have a HP Jornada 620/660/680/690 and want to
support the built-in keyboard.
