Subject: [PATCH] drm/edid: Increase size of VDB and CMDB bitmaps to 256 bits
Date: Tue, 10 Dec 2019 14:10:48 -0800	[thread overview]
Message-ID: <20191210221048.83628-1-thomasanderson@google.com> (raw)

CEA-861-G adds modes up to 219, so increase the size of the
maps in preparation for adding the new modes to drm_edid.c.
