Subject: [PATCH 18/31] staging: bcm2835-camera: Set sequence number correctly
Date: Thu, 27 Jun 2019 20:56:15 +0200	[thread overview]
Message-ID: <1561661788-22744-19-git-send-email-wahrenst@gmx.net> (raw)
In-Reply-To: <1561661788-22744-1-git-send-email-wahrenst@gmx.net>

From: Dave Stevenson <dave.stevenson@raspberrypi.org>

Set the sequence number in vb2_v4l2_buffer mainly so the
latest v4l2-ctl reports the frame rate correctly.

Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
