The code I pointed to, https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/char/virtio_console.c#n1993 either enables remoteproc if the module is present; or it enables multiport, but not both at the same time. If remoteproc isn't present when this probe routine is executed, multiport might get enabled. And then there's no chance for remoteproc to get enabled. Amit
