I think now you're passing also dev->platform_data for all the
other devices as this gets called for any devices added.
So you probale should use something like this instead:
if (!strcmp("twl4030-gpio", dev_name(dev)))
dev->platform_data = &twl_gpio_auxdata;
if (!strcmp("twl4030-whatever-you-need", dev_name(dev)))
dev->platform_data = &twl_gpio_auxdata;
