Sorry about not getting back to you sooner, life got in the way. The
problem here is that the dvb-usb-cxusb did not get selected, so it
was not recompiled.
The problem is that DVB_USB_CXUSB Kconfig has this line:
select DVB_SI2168 if MEDIA_SUBDRV_AUTOSELECT
The make_kconfig.pl script transforms this into a dependency, but
DVB_SI2168 is only available when compiling against kernel 4.7 or later.
I think only one select line needs to match, so I created this patch.
Please apply this patch against media_build, you might need to do make
clean before building again.
Thanks,
Sean
