You make it sound like a bad thing.

The reality is that I see no point in putting code into a driver where 
the needed logic has already been implemented elsewhere.  Especially 
with IR, there's questions about what IR remote you are using, if you 
want to use multiple IR remotes, if you want to map IR events to 
keypresses, etc.  Different people are going to want to configure things 
like that in different ways.  That's a lot of work that would all be 
redundant in the pvrusb2 driver since it's been done elsewhere already.

The situation with this new device is the same as it still is for the 
29xxx models - the pvrusb2 driver implements access to the chip same as 
any other I2C chip in the device, leaving another entity (e.g. lirc) to 
implement a driver for the chip.  The exception was for the 
non-IR-transmitting (for lack of a better designator) 24xxx devices, 
where the IR receiver function wasn't on the I2C bus and would have 
otherwise been completely inaccessible.  In that case I had to do 
something to let other things "see" it and I did that by emulating the 
29xxx model's I2C-resident IR receiver chip.  This new 24xxx model is 
using a different IR receiver that is once again accessible via the I2C 
bus, so the correct strategy once again is to do nothing and let lirc 
(or any other appropriate module) drive it.

It would probably also be useful to post here specifically what you did 
to get it working, once you have it working.  (Or for that matter, hint, 
hint, anyone else who has walked through the process of getting the new 
IR receiver working with lirc would be welcome to post details here...)
