From e4f53a4d921eba6187a2599cf184a3beeb604fe2 Mon Sep 17 00:00:00 2001 From: Chris Morgan Date: Mon, 4 Dec 2023 12:57:11 -0600 Subject: [PATCH] drm/panel: himax-hx8394: Drop shutdown logic The driver shutdown is duplicate as it calls drm_unprepare and drm_disable which are called anyway when associated drivers are shutdown/removed.
