Subject: [PATCH 05/13] media: i2c: Add .get_selection() support to ov8865
Date: Thu, 22 Jul 2021 21:33:59 +0100	[thread overview]
Message-ID: <20210722203407.3588046-6-djrscally@gmail.com> (raw)
In-Reply-To: <20210722203407.3588046-1-djrscally@gmail.com>

The ov8865 driver's v4l2_subdev_pad_ops currently does not include
.get_selection() - add support for that callback.
