In the error case, the other GPIO is not freed. Also maybe you should
free them on module removal, because now the module owns the GPIOs.

Wouldn't the usage of devm_* functions take care of this? If the device isn't registered successfully, then all allocations/requests done using devm_* functions will be free'd automatically.
