From 5d96738d9a74ec774bc7408288b44a7db6321c47 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Tue, 29 Oct 2019 17:04:02 -0700 Subject: [PATCH] Input: cobalt_btns - 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 cobalt_btns driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV.
