From 96adb419099cc042962c66cec6cd2ad905fee181 Mon Sep 17 00:00:00 2001 From: Benjamin Berg Date: Mon, 23 Nov 2020 14:21:57 +0100 Subject: [PATCH] platform/x86: thinkpad_acpi: Send tablet mode switch at wakeup time The lid state may change while the machine is suspended. As such, we may need to re-check the state at wake-up time (at least when waking up from hibernation). Add the appropriate call to the resume handler in order to sync the SW_TABLET_MODE switch state with the hardware state.
