Hi Ben,

I was thinking about that. But then again, I'd either have to copy the 
client->dev.platform_data pointer over to the private data, if it is non-null, 
or I would have to use some variation of

pdata = client->dev.platform_data ? client->dev.platform_data : priv_pd;

every time I want to access the configuration. Guess, that's not so bad though.

Thanks,
Frank
