Subject: media: i2c: imx334: Drop check for reentrant .s_stream()
Author: Laurent Pinchart <laurent.pinch...@ideasonboard.com>
Date: Thu Sep 14 21:16:16 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.
The streaming field of the driver's private structure is now unused,
drop it as well.
