Subject: [PATCH 14/22] Input: sgi_btns - switch to using polled mode of input devices
Date:   Thu, 17 Oct 2019 13:42:08 -0700
Message-Id: <20191017204217.106453-15-dmitry.torokhov@gmail.com>

Precedence: bulk

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