Subject: [PATCH] gpio: max732x: fix input configuration for open-drain pins

Eric,

The attached patch tries to fix a bug I noticed while hacking on the
max732x driver for interrupt support.
According to the datasheets, open-drain pins have to be configured as
output-high (which in that case is actually high impedance) to be used as
input.

Note that this patch has only been compile tested, as I still have to
solder the actual chip to one of my boards...

Thanks,

        M.
