From 059ea4e591abd40d0726d22c38b29f4b5c99cb73 Mon Sep 17 00:00:00 2001
From: Julian Parkin <julian.parkin@amd.com>
Date: Mon, 12 Aug 2019 18:47:50 -0400
Subject: [PATCH 3836/4256] drm/amd/display: Separate hardware initialization
from creation
[Why]
Separating the hardware initialization from the creation of the
dc structures gives greater flexibility to the dm to override
options for debugging.
[How]
Move the hardware initialization call to a new function,
dc_hardware_init. No functional change is intended.
