Subject: [PATCH] media: ov5695: Off by one in ov5695_enum_frame_sizes()
Date: Thu, 01 Mar 2018 10:07:14 +0000	[thread overview]
Message-ID: <20180301100714.GA14140@mwanda> (raw)

The ">" should be ">=" so that we don't read one element beyond the end
of the array.

Fixes: 8a77009be4be ("media: ov5695: add support for OV5695 sensor")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
