Macmini pins in sigmatel_audio

[Nicolas Boichat <nicolas@boichat.ch>]

Hi,

I just got this input from a Macmini user (subsys id: 0x106b0800), after
asking him to try different pins settings. (the sound doesn't work
properly with a vanilla 2.6.21-rc3 kernel)

Considering these pins have been used for a long time on mactel-linux,
and that they are working fine with MacBook (1st generation at least),
Macmini and Macbook Pro (1st generation only), I think the following
patch is appropriate (please apply it after the patch sent yesterday).

Best regards,

Nicolas

Fix audio on Macmini and Macbook.
