usb4_switch_remove_ports(9)

okay so bestie, welcome to usb4_switch_remove_ports(9) from the Kernel API Manual — it's giving tiny kernel-API page, and we're literally about to unregister some USB4 ports ✨💅

🎀 NAME 🎀

usb4_switch_remove_ports — Removes USB4 ports from this router

✨ SYNOPSIS ✨

void usb4_switch_remove_ports (struct tb_switch *sw );

🌸 ARGUMENTS 🌸

• sw — the USB4 router, bestie. That's the router whose ports are getting handled here. 🫶

🦋 DESCRIPTION 🦋

Unregisters the USB4 ports that were previously registered. That's the whole vibe: ports that were registered before get unregistered here, no cap. 💖
