It is a sort of standard to use dvb_* for pure digital tv
bridge drivers.

Yet, I agree with you that at least an alias is needed.
earlier today, I wrote a patch with such purpose:

	https://patchwork.linuxtv.org/project/linux-media/patch/fccf254e33bdd169dde6bdd6f941cf773c82a1c0.1599901499.git.mchehab+huawei@kernel.org/

Still, maybe we should move dvb_vidtv_tuner.ko and dvb_vidtv_demod.ko
to dvb-frontends and rename them. Not 100% sure about that, though.

I would also rename vidtv_bridge.c to just vidtv.c.


Thanks,
Mauro
