Subject: [PATCH v2] drm/i915: Support HDMI EDID injection
Date: Wed,  3 Feb 2016 18:49:09 +0200	[thread overview]
Message-ID: <1454518149-10421-1-git-send-email-marius.c.vlad@intel.com> (raw)
In-Reply-To: <1454418061-10178-1-git-send-email-marius.c.vlad@intel.com>

Make a copy of drm_property_blob data for user-supplied EDID blobs.

v2: Allocate and memcopy drm_property_blob->data instead of pointing
to it.
