Astrometa DVB-T2 not working correctly with Kernel 4.6

Hello everybody,

I own this TV stick:

https://www.linuxtv.org/wiki/index.php/Astrometa_DVB-T2

It uses different chips to decode DVB-T and DVB-T2 streams, the required modules are rtl2832 and mn88473.
Up until linux 4.5 it worked correctly, in 4.6 only DVB-T works.
In 4.6 the mn88473 module isn’t loaded automatically and can’t be loaded manually, since it doesn’t exist in the system.

In 4.6 the module has been moved from staging to dvb-frontends.
I tried to build it with

make M=drivers/media/dvb-frontends

which gave me *.ko files for the other frontends, but not for mn88473.

I attached the relevant output of dmesg.

Regards
Ferda
