Subject: [PATCH v3 4/5] [media] s5p-mfc: Set last buffer flag
Date: Fri, 6 Mar 2015 11:18:29 +0100 [thread overview]
Message-ID: <1425637110-12100-5-git-send-email-p.zabel@pengutronix.de> (raw)
In-Reply-To: <1425637110-12100-1-git-send-email-p.zabel@pengutronix.de>
Setting the last buffer flag causes the videobuf2 core to return -EPIPE from
DQBUF calls on the capture queue after the last buffer is dequeued.
