Subject: media: i2c: ov9734: Drop check for reentrant .s_stream()
Author:  Laurent Pinchart <laurent.pinch...@ideasonboard.com>
Date:    Thu Sep 14 21:16:37 2023 +0300

The subdev .s_stream() operation shall not be called to start streaming
on an already started subdev, or stop streaming on a stopped subdev.
Remove the check that guards against that condition.
