Analyze and fix the following issue in the Linux kernel code: [media] omap3isp: Prevent pipelines that contain a crashed entity from starting
Problem Details: 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 ...
