Would you like me to help you with this platform data. This GPIO thing is
breaking mioa701 GSM chip (not damaging this time :)), so would you like me to
cook up the platform data passed to pxa2xx-ac97, and amend my patch accordingly

Or have you already coded the beast in your working repository ?



PS: passing that platform data is easy, I should have done it right from the
start. I can't see how I missed the simple platform_data in pxa2xx_ac97 probe
function ... grrr... Must be the belgian food I tried.
