Subject: [PATCH v15 13/19] media: subdev: add streams to v4l2_subdev_get_fmt() helper function
Date: Mon,  3 Oct 2022 15:18:46 +0300	[thread overview]
Message-ID: <20221003121852.616745-14-tomi.valkeinen@ideasonboard.com> (raw)
In-Reply-To: <20221003121852.616745-1-tomi.valkeinen@ideasonboard.com>

Add streams support to v4l2_subdev_get_fmt() helper function. Subdev
drivers that do not need to do anything special in their get_fmt op can
use this helper directly for v4l2_subdev_pad_ops.get_fmt.
