After the first moment where tuner-xc2028 returns a negative value, it stops
receiving later commands. this explains the error on line 1080. On USB devices,
it only recovers after unplugging/replugging it. I'm not sure if just removing
saa7134 and reinserting will revive the tuner.

I did a small change on the enclosed patch. Hopefully, this way, the tuner will
reborn. Otherwise, you may need to reboot the machine.

You're welcome.
