Subject: [RESEND PATCH v2] drm/panel: synaptics-r63353: Fix regulator unbalance
From: Michael Trimarchi <michael@...rulasolutions.com>
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.
