Laurent Pinchart 1567bb7dcc [media] omap3isp: Prevent pipelines that contain a crashed entity from starting ... The OMAP3 ISP preview engine will violate the L4 bus protocol if we try to write some of its internal registers after it failed to stop properly. This generates an external abort on non-linefetch fault, triggering a fatal kernel oops. We can't always prevent preview engine stop failures (they can for instance be caused by a sensor crash), but we can improve the system reliability by refusing to start streaming on a pipeline that contains the preview engine if it failed to stop. The driver will then eventually reset the ISP (when all applications will have closed their file handles related to OMAP3 ISP device nodes), making the ISP usable again.
