[mythtv] 25-fixes compile error V4L2_MPEG_AUDIO_ENCODING_AC3

[Dave Badia]

I did a git update to the latest 25-fixes last night and I'm getting
the compile error below.  Tried clean distclean but still see the
problem.

I see that V4L2_MPEG_AUDIO_ENCODING_AC3 was introduced in the
following commit, is there some new kernel version/hdpvr driver
requirement with this change?
