ci_hdrc_pci_remove(9)

💅 ci_hdrc_pci_remove(9) 💅

okay bestie, so this is a page straight out of the Kernel API Manual — yes, that's the whole manual name, we're fancy here — and it's about one very specific little function. buckle up, it's short but it's iconic 🎀

---

✨ NAME ✨

ci_hdrc_pci_remove — literally just "PCI remove". that's the whole name section, no notes, slay 🫶

---

✨ SYNOPSIS ✨

void ci_hdrc_pci_remove (struct pci_dev *pdev );

that's it. that's the vibe check. it returns void, meaning it gives you nothing back — no cap, zero return value, it just does the thing and dips 💅

---

✨ ARGUMENTS ✨

• pdev — the USB Device Controller that's getting removed. yes, it's a struct pci_dev * and yes, it's the star of the show. main character energy fr fr 👑

---

✨ DESCRIPTION ✨

so the way this works: this function is the undo button for ci_hdrc_pci_probe — it reverses whatever that probe got up to. lowkey the cleanup queen 🌸

how does it undo things, you ask? in two very specific steps, in this exact order (the order matters, bestie, don't come for me):

1. first it invokes udc_remove — yeah, that one, exactly that name, iykyk
2. then it releases all the PCI resources that got allocated for this USB device controller

so it's first the udc_remove, then the PCI resources get freed. that sequence is the whole point. no shortcuts, no reordering, we respect the sequence here ✨

no undefined behaviour warnings on this one, she's a clean, well-behaved little teardown function. but still — it's a remove function, so it's doing destructive-ish cleanup by nature. treat her with respect 🧚

---

✨ SEE ALSO ✨

• the kernel file itself: ./drivers/usb/chipidea/ci_hdrc_pci.c — go read it, it's right there
• ci_hdrc_pci_probe(9) — the one this function is un-doing. the prequel. the origin story. go check it out 🔥

---

and that's the whole page, bestie — short, sweet, and to the point 🦋

cute little sign-off: this one lives under ./drivers/usb/chipidea, it's dated October 2026, and the page itself answers to the name ci_hdrc_pci_remove(9). periodt 💖🎀⭐
