I've no idea who tagged the ivtv-firmware package as obsoleted.

The status of the firmwares is that almost all ivtv firmwares
are part of linux-firmware. However, we didn't manage to get
an ack from Conexant (or Hauppauge) to release a few firmwares
using a license that would allow redistribution. The problem
is that those firmwares are for hardware that are discontinued
by the chipset manufacturer.

So, those should still be released using the license that
was granted on this package.

So, IMO, those files should be kept at the package:
	/lib/firmware/ivtv-firmware-license-end-user.txt
	/lib/firmware/ivtv-firmware-license-oemihvisv.txt
	/lib/firmware/v4l-cx2341x-enc.fw
	/lib/firmware/v4l-pvrusb2-24xxx-01.fw
	/lib/firmware/v4l-pvrusb2-29xxx-01.fw
	/usr/share/doc/ivtv-firmware
	/usr/share/doc/ivtv-firmware/license-end-user.txt
	/usr/share/doc/ivtv-firmware/license-oemihvisv.txt

The other files should be replaced by the ones at linux-firmware,
with has a better license that allows redistribution.

Mauro
