I'll take care of that. I also discovered that one call to vb2_core_reqbufs()
wasn't updated (in drivers/media/dvb-core/dvb_vb2.c). I've fixed that as well.

All my regression tests passed, so I plan to post a PR for 5.9 reverting this
feature soon.

Many thanks to everyone for 1) discovering this problem and 2) creating a patch
to revert this.

Regards,
