vhost/vsock: use static minor number
Vhost-vsock is a software device so there is no probe call that causes the driver to register its misc char device node. This creates a chicken and egg problem: userspace applications must open /dev/vhost-vsock to use the driver but the file doesn't exist until the kernel module has been loaded. Use the devname modalias mechanism so that /dev/vhost-vsock is created at boot. The vhost_vsock kernel module is automatically loaded when the first application opens /dev/host-vsock. Note that the "reserved for local use" range in Documentation/admin-guide/devices.txt is incorrect. The userio driver already occupies part of that range. I've updated the documentation accordingly.
