Subject: [PATCH v2 32/35] media: ti-vpe: cal: use CSI-2 frame number
Date: Tue, 20 Apr 2021 15:04:30 +0300
Message-ID: <20210420120433.902394-33-tomi.valkeinen@ideasonboard.com> (raw)
In-Reply-To: <20210420120433.902394-1-tomi.valkeinen@ideasonboard.com>

The driver fills buf->vb.sequence with an increasing number which is
incremented by the driver. This feels a bit pointless, as the userspace
could as well track that kind of number itself. Instead, lets use the
frame number provided in the CSI-2 data from the sensor.
