From dac4c2eb4fe667f569ed7ddea9c43382fd88f4eb Mon Sep 17 00:00:00 2001
From: Harry Wentland <harry.wentland@amd.com>
Date: Tue, 12 Sep 2017 20:04:48 -0400
Subject: [PATCH 2403/4131] drm/amd/display: Reduce DC chattiness
Log DC init but default log level to 0 (default for
amdgpu_dc_log) otherwise. Bug reporters can still make
DC more chatty by using the dc_log module param.
amdgpu.dc_log = 1
v2: Only provide runtime option, no compile time config
Change-Id: I2443c67546ced94531026bfe06533a4db51e8a73
Signed-off-by: Harry Wentland <harry.wentland@amd.com>
