[Bug 1944541] Re: tvservice fails

[Dave Jones]

This is indeed down to the (deliberately) outdated userland package.
While this should be fixed for Jammy, the older series are a trickier
prospect as bumping the userland version will remove mmal supported on
arm64 (this is also the case for Jammy, but libcamera is intended to be
the replacement for the legacy camera utilities there).

I'll leave the targetting on the older series for now, pending a
decision on whether it's possible to backport a specific patch for
tvservice.

** No longer affects: linux-raspi (Ubuntu)

** Also affects: raspberrypi-userland (Ubuntu Jammy)
   Importance: Undecided
       Status: New

** No longer affects: linux-raspi (Ubuntu Focal)

** No longer affects: linux-raspi (Ubuntu Hirsute)

** No longer affects: linux-raspi (Ubuntu Impish)

** Changed in: raspberrypi-userland (Ubuntu Jammy)
