+Subject: Bluetooth: allocate static minor for vhci
+
+Commit bfacbb9 (Bluetooth: Use devname:vhci module alias for virtual HCI
+driver) added the module alias to hci_vhci module so it's possible to
+create the /dev/vhci node. However creating an alias without
+specifying the minor doesn't allow us to create the node ahead,
+triggerring module auto-load when it's first accessed.
+
+Starting with depmod from kmod 16 we started to warn if there's a
+devname alias without specifying the major and minor.
+
+Let's do the same done for uhid, kvm, fuse and others, specifying a
+fixed minor. In systems with systemd as the init the following will
+happen: on early boot systemd will call "kmod static-nodes" to read
+/lib/modules/$(uname -r)/modules.devname and then create the nodes. When
+first accessed these "dead" nodes will trigger the module loading.
