You can add multiple MODULE_ALIASES if needed. > MODULE_AUTHOR("Jonathan Cormier <jcormier@xxxxxxxxxxxxxxxx>"); > -MODULE_DESCRIPTION("TPS65219 GPIO driver"); > +MODULE_DESCRIPTION("TPS65215/TPS65219 GPIO driver"); "TPS6521x GPIO driver"? I also see a product named TPS65216. By any chance can that be also supported by this driver? > MODULE_LICENSE("GPL"); -- cheers, -roger
