So if I understand correctly, we can guarantee that the delayed work will not execute until the device driver probe() has finished, and it *will* execute immediately after that? So: - Device driver probes - Delayed work is called - Next initcall I'm not 100% familiar with how delayed work works... :/ Yours, Linus Walleij -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
