This is part of the generic code.  It's main purpose is to provide basic
support until full featured support is created for a system.  If there
are systems that need this patch to work, we should look into adding
them to the main patch_* codec drivers.

For example, the Conexant codecs are now getting supported directly, as
are via and atihdmi.

If you have some information on these Panasonic models, please forward
it to me, thanks.
