From 5ee19cda8136a877c9ec1433eb805b220c219c42 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Tue, 5 May 2020 11:09:51 -0600 Subject: mb/google/kahlee: Don't reset the touchpad/screen on boot touchpad & touchscreen power enable gets reset during resume causing unintended wake interrupts, causing dark resume failures. This prevents the board from being shut down after it's been suspended for a long period of time and can end up draining the battery.
