The change log entry said:

   This means that the alignment between 'odd/even' and
    'clean/dirty' might take a little longer to attain,

how ever the code makes no attempt to create that alignment, so it
could take arbitrarily long.

So when we find that clean/dirty is not aligned with odd/even,
force a second metadata-update immediately.  There are already cases
where a second metadata-update is needed immediately (e.g. when a
device fails during the metadata update).  We just piggy-back on that.

An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix
regression where v4l2_device was registered too late) caused a new
regression in the av7110 driver.

Reverted the old fix and fixed the problem in the mxb driver instead.
Tested on mxb and budget-av cards.

The real problem is that the saa7146 framework has separate probe()
and attach() driver callbacks which should be rolled into one. This
is now done for the mxb driver, but others should do the same. Lack
