In fact, you are breaking the hinic_get_channels() function which is properly advertising the ->max_* values currently. Now it will return zero. Whatever is advertised in ->max_* should be the driver's maximum capabilities. This means that the user can request anything in the range from '1' to these max values. Whatever the user asks for in ->combined_count and elsewhere, you _MUST_ provide or return an error. That is not what hinic_set_channels() is doing. It is using combined_count as a "limit" rather than the value to use.
