Sorry if I sent the patch at a wrong time...

I'm not changing the MFD driver, the first version is hopefully going
into the v. 2.6.38 kernel.

At first I started to upstream all three parts of the driver at the same
time, about a year ago. At first I sent all parts to the media list,
there I was - quite reasonably - asked to send the codec to the alsa
list. After some tuning and fine tuning the codec got accepted. But
getting the rest of the driver in took much longer and in the process
the MFD and V4L2 parts became incompatible with the codec.

So we'll just wait until 2.6.38 is out and everything remains
compilable... When 38 gets released the codec cannot be used with rest
of the driver until this patch is applied, but that can be done when a
suitable window opens, right?
