You missed something, but it turns out not to be a build problem as such on
closer inspection.
I got confused by this code in drivers/media/dvb/Kconfig:
comment "Supported FireWire (IEEE 1394) Adapters"
depends on DVB_CORE && IEEE1394
source "drivers/media/dvb/firewire/Kconfig"
Since the comment depends on IEEE1394 it disappeared once IEEE1394 was removed.
So when I looked for this comment in the menu is was no longer there. But the
actual driver still is, and I missed that.
So it was just the comment dependency that was wrong, not the driver itself.
Sorry for the confusion.
