Subject: [Intel-gfx] [PATCH v3 5/7] drm/i915/hdcp: Fill wired_cmd_in structures at a single place
Date: Wed, 14 Dec 2022 14:37:56 +0530 [thread overview]
Message-ID: <20221214090758.3040356-6-suraj.kandpal@intel.com> (raw)
In-Reply-To: <20221214090758.3040356-1-suraj.kandpal@intel.com>
Need to fill wired cmd in structures at a single place as they remain
same for both gsc and mei.
--v3
-remove inline function from header [Jani]
