Well, if you suspect that some other change broke the driver, then you can try an older kernel (the support was introduced in kernel 3.10) or an older media_tree to see if that's indeed the case.
The firmware is just one small piece of the puzzle. Maybe you can just replace the firmware or maybe you need to write a lot of code or even both. All this is next to impossible to say without having a very strictly defined and pinpointed issue or alternatively the actual device to play around with. So far it seems you're the only one with that device here, so it would help a lot if you can narrow the scope down by saying: "it worked fine in kernel xyz, but commit abc seems to break the support for the device" or "it seems it has never worked for DVB-T".
