The Vortex PCIe card by Prospero Technologies Ltd is a modular DVB card with a hardware demux, the card can support up to 8 modules which are fixed to the board at assembly time. Currently we only offer one configuration, 8 x Dibcom 7090p DVB-t tuners, but we will soon be releasing other configurations. There is also a connector for an infra-red receiver dongle on the board which supports RAW IR. The driver has been in testing on our systems (ARM Cortex-A9, Marvell Sheva, x86, x86-64) for longer than 6 months, so I'm confident that it works. However as this is the first Linux driver I've written, I'm sure there are some things that I've got wrong. One thing in particular which has been raised by one of our early testers is that we currently register all of our frontends as being attached to one adapter. This means the device is enumerated in /dev like this: /dev/dvb/adapter0/frontend0 /dev/dvb/adapter0/dvr0 /dev/dvb/adapter0/demux0 /dev/dvb/adapter0/frontend1 /dev/dvb/adapter0/dvr1 /dev/dvb/adapter0/demux1 /dev/dvb/adapter0/frontend2 /dev/dvb/adapter0/dvr2 /dev/dvb/adapter0/demux2 etc. Whilst I think this is ok according to the spec, our tester has complained that it's incompatible with their software which expects to find just one frontend per adapter. So I'm wondering if someone could confirm if what I've done with regards to this is correct.
As I understand all those tuners are independent (could be used same time) you should register those as a 8 adapters, each having single frontend, dvr and demux.

I've tested this patch by applying it to current media-master and it applies cleanly and builds without issue for me.
