Great step forward. Thanks.

In my opinion, it would be great to handle all fixups in some "user
space" compatible mode. I mean, do not use the C code for fixups, but
use an universal description code which can be loaded from the user
space probably as ASCII text (firmware like behaviour), too. This code
can be buildin to the kernel modules in a default version. I don't mean
the current implemented patch processing, but full codec initialization.
I think that it may be last change to bring the HDA code to more
maintenable state. Just an idea to avoid further HDA code rewrites which
happen periodically. And now (with your rewrite) it's really good time
to propose also this change.

Please, provide the GIT URL with these changes.

					Thanks,
