[patch] tvmixer update

[patch] tvmixer update

[Gerd Knorr]

  Hi,

This patch updates the tvmixer.  Basically fixes the build failure
due to the recent i2c updates.  It uses the new i2c_clientname()
function introduced by a patch sent earlier today and thus depends on
that patch being applied.

  Gerd
