I don't understand the "anything". What should be done if pdata is passed with
reset_gpio = 0 then ?

Should this be considered as the default case and transformed into 113 ? That
sounds a bit buggy, because if someone changes his code to include platform_data
support, they'll have to init platform_data anyway, and fill in reset_gpio

Should this be handled like a casual gpio (ie. gpio 99) ?
