Subject: [PATCH] drm/radeon: Provide ddc symlink in connector sysfs directory
Date: Thu, 1 Aug 2019 18:36:38 +0200 [thread overview]
Message-ID: <20190801163638.17957-1-andrzej.p@collabora.com> (raw)
In-Reply-To: <7cacac43-737e-1ddb-2951-394fcf9ad0b2@baylibre.com>
Use the ddc pointer provided by the generic connector.
Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@collabora.com>
---
This is the same patch as in the series:
https://www.spinics.net/lists/dri-devel/msg220128.html
but this time without a bug.
radeon_add_legacy_connector() uses a local ddc variable, but it has
not been declared in the previous version of this patch.
Compile tested.
