From a quick glance, there seem to be messages for when the device is _not_ bound to the fsl-mc driver (e.g. in vfio_fsl_mc_bus_notifier()); I'd just fix the typo for now. > --- > drivers/vfio/fsl-mc/vfio_fsl_mc.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) Acked-by: Cornelia Huck <cohuck@redhat.com>

Having to decide between losing the WARN and losing the device info, I'd just... fix the typo :)
