[PATCH 12/22] Input: cobalt_btns - switch to using polled mode of input devices

From: Dmitry Torokhov
Date: Thu Oct 17 2019 - 16:43:26 EST


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

Say Y here if you want to support MIPS Cobalt button interface.
