[23/57] media: i2c: ov5647: Drop check for reentrant .s_stream()

Commit Message

Laurent Pinchart Sept. 14, 2023, 6:16 p.m. UTC

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.
