V4L/DVB (9361): Dynamic DVB minor allocation
Implement dynamic minor allocation for DVB, to allow more than four devices of the same type per adapter, based on drivers/usb/core/file.c. Add a new config option, DVB_DYNAMIC_MINORS, to make use of this feature, which defaults to no for backwards compatibility.

+ help
+ If you say Y here, the DVB subsystem will use dynamic minor
+ allocation for any device that uses the DVB major number.
+ This means that you can have more than 4 of a single type
+ of device (like demuxes and frontends) per adapter, but udev
+ will be required to manage the device nodes.
+
+ If you are unsure about this, say N here.
