Nicholas, maybe the kernel could ignore such > no-op property "updates"? Even if it's no-op update it's still going to be locking the connector and potentially blocking other commits from occurring so ideally the client userspace wouldn't be dong this. I can try writing up a patch that doesn't lock everything if the connector state hasn't change at the very least but I'm not sure if it will fully address the issue or not.
