From dc9dc864f35dd3b87d52fbe9809773576ac77d32 Mon Sep 17 00:00:00 2001 From: Ping Cheng Date: Mon, 19 Jul 2021 13:55:29 -0700 Subject: HID: wacom: set initial hardware touch switch state to 'off' Wacom touch devices have two types of touch switches: softkey touch toggle and hardware touch switch. For softkey toggle, we assume touch is on by default in the driver. However the hardware touch switch is controlled by end users. We don't know if it's on or off before getting the status event. This patch sets touch off for devices with a hardware switch until we get the status. This is a bit safer for users who leave the switch "off" and don't want any accidental touches. The tradeoff is a slight delay between device connection and touch becoming enabled for users who leave the switch "on".
