[PATCH v3 05/12] drm/bridge: ti-sn65dsi86: Move drm_panel_unprepare() to post_disable()

From: Douglas Anderson
Date: Fri Apr 02 2021 - 18:29:42 EST


We prepared the panel in pre_enable() so we should unprepare it in
post_disable() to match.

This becomes important once we start using pre_enable() and
post_disable() to make sure things are powered on (and then off again)
when reading the EDID.
