Even without async function calls this is dicey and not correct, but with async function calls during the boot sequence this is going to get hit more... This patch adds the synchronization using the newly introduced helper. Signed-off-by: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx> Signed-off-by: Rafael J.
