Use “const char *variant”. Yeah, also as I mentioned earlier, this function has all the information to determine the variant itself, there is no need to clutter btusb_setup_qca_load_nvm() and the interface of this function with variant stuff, it should be internal business of btusb_generate_qca_nvm_name(). > > > + char *sep = (strlen(variant) == 0) ?

the RF performance of wcn6855 soc chip from different foundries will be difference, so we should use different nvm to configure them.
