From d2bd3fcb825725a59c8880070b1206b1710922bd Mon Sep 17 00:00:00 2001 From: Michael Trimarchi Date: Thu, 5 Dec 2024 17:29:58 +0100 Subject: [PATCH] drm/panel: synaptics-r63353: Fix regulator unbalance The shutdown function can be called when the display is already unprepared. For example during reboot this trigger a kernel backlog. Calling the drm_panel_unprepare, allow us to avoid to trigger the kernel warning.
