pcie_port_bus_remove(9)

💅 pcie_port_bus_remove(9) ✨

okay so this is a page from the Kernel API Manual, bestie — and it's literally about detaching a driver from a PCI Express port service device. tiny function, big responsibilities. let's get into it 🫶

---

✨ NAME ✨

pcie_port_bus_remove — detach driver from given PCI Express port service 💅

---

🌸 SYNOPSIS 🌸

void pcie_port_bus_remove (struct device *dev );

---

🎀 ARGUMENTS 🎀

• dev — the PCI Express port service device we're handling 🦋 (like, this is the one being dealt with, ok?)

---

💖 DESCRIPTION 💖

so here's the vibe: if a PCI Express port service driver is registered with pcie_port_service_register, then this function is gonna get called by the driver core ✨ — specifically when device_unregister is called for the port service device that's associated with that driver. no cap, that's the whole flow 💫
