    Bluetooth: allocate static minor for vhci · b075dd40

    Commit bfacbb9a (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.
