These looks OK to me. Could you regenerate patches against the latest
git (or ALSA CVS) ?

Or, it might be better against to mm tree, since pnp registrations
will be modified there, too. They should go also to mainstream
together.

Will do.

Attached. This was in fact really just regenerating (against 2.6.16-mm1)
Description:

If platform_driver_register_simple() now returns the probe() method error, the init loop should not bail on the first IS_ERR, but try the next one.
