Subject: [PATCH 10/17] drm/i915/icl: initialize MBus during display init
Date: Tue, 23 Jan 2018 17:05:29 -0200	[thread overview]
Message-ID: <20180123190536.11208-11-paulo.r.zanoni@intel.com> (raw)
In-Reply-To: <20180123190536.11208-1-paulo.r.zanoni@intel.com>

From: Mahesh Kumar <mahesh1.kumar@intel.com>

This patch initializes MBus during display initialization.

Changes since V2 (from Paulo):
 - Don't forget to remove the WARN_ON(1) call.
Changes since V1:
 - Rebase to use function like Macros
