+ bool "Dynamic DVB minor allocation"
+ depends on DVB_CORE
+ default n
+ 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.
