Subject: media: ov2680: Read and log sensor revision during probe
Author: Hans de Goede <hdego...@redhat.com>
Date: Thu Aug 3 11:33:42 2023 +0200
Read and log sensor revision during probe.
Since this means that the driver will now already log a message on
successful probe drop the "ov2680 init correctly" log message.
