From f829d76234515eb69fa1632ec51f11f03ace6696 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Revert "drm/panel: Initialise panel dev and funcs through
 drm_panel_init()"

This reverts commit 362940f8e40ff27211c21924c5cf18fa9c7c650e which is
commit 6dbe0c4b0fc0646442b2b1580d022404e582fd7b upstream.

It breaks the Android abi and is not needed for any Android systems.  If
it is required in the future, it can come back in an abi-safe way.

Bug: 161946584
Change-Id: I4df07557f05d05ef1d0762a5392ed7203894fb56
