Subject: [PATCH v6 05/18] media: vsp1: Replace the display list internal flag with a flags field
Date: Wed, 13 Mar 2019 02:05:19 +0200	[thread overview]
Message-ID: <20190313000532.7087-6-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20190313000532.7087-1-laurent.pinchart+renesas@ideasonboard.com>

To prepare for addition of more flags to the display list, replace the
'internal' flag field by a bitmask 'flags' field.
