Subject: [PATCH 01/22] Input: raspberrypi-ts - switch to using polled mode of input devices
Date: Thu, 17 Oct 2019 13:41:55 -0700 [thread overview]
Message-ID: <20191017204217.106453-2-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20191017204217.106453-1-dmitry.torokhov@gmail.com>
We have added polled mode to the normal input devices with the intent of
retiring input_polled_dev. This converts raspberrypi-ts driver to use the
polling mode of standard input devices and removes dependency on
INPUT_POLLDEV.
