Subject: [PATCH 3.18 02/27] drm/dp/mst: save vcpi with payloads
Date: Thu, 19 Oct 2017 15:49:08 +0200 [thread overview]
Message-ID: <20171019134844.666272341@linuxfoundation.org> (raw)
In-Reply-To: <20171019134844.523725420@linuxfoundation.org>
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Harry Wentland <harry.wentland@amd.com>
commit 6cecdf7a161d2b909dc7c8979176bbc4f0669968 upstream.
This makes it possibly for drivers to find the associated
mst_port by looking at the payload allocation table.
