🌸 NAME 🌸

pci_epc_remove_epf — remove PCI endpoint function from endpoint controller

like, literally the "un-invite from the group chat" of the PCI endpoint world 💅

---

✨ SYNOPSIS ✨

void pci_epc_remove_epf (struct pci_epc *epc , struct pci_epf *epf ,
       enum pci_epc_interface_type type );

no cap, that's the whole signature — returns void, so no exit status drama here, it just does the thing 🎀

🦋 ARGUMENTS 🦋

• epc — the EPC device from which the endpoint function should be removed. yeah, the one getting ghosted 💀
• epf — the endpoint function to be removed. this is the one being softly un-added, no hard feelings 💖
• type — identifies if the EPC is connected to the primary or secondary interface of EPF. it's giving "which side of the group chat are we on" energy, iykyk 🌈
