comedi_pci_auto_unconfig(9)

💅 comedi_pci_auto_unconfig — like, the Kernel API Manual page, bestie

okay so this is comedi_pci_auto_unconfig(9) from the Kernel API Manual, and honestly? it's giving "cleanup era" and we're obsessed 🧹✨

---

✨ NAME ✨

comedi_pci_auto_unconfig — unconfigure/remove a PCI COMEDI device 🫶

---

🌸 SYNOPSIS 🌸

void comedi_pci_auto_unconfig (struct pci_dev *pcidev );

that's it, that's the whole vibe. one function, one argument, zero drama 💅

---

🎀 ARGUMENTS 🎀

• pcidev — the PCI device. yeah. that one. the PCI device 💖

---

🦋 DESCRIPTION 🦋

okay so picture this: you're in the pci_driver (*remove) function — that's typically where this gets called, iykyk — and it's time to auto-unconfigure a COMEDI device that's attached to this PCI device. 🧚

and like, how does it know which hardware device? it uses a pointer to the struct device embedded in *pcidev as the hardware device. slay, embedded structs, iconic behavior 👑

here's the part where the COMEDI driver's "detach" handler gets called — it happens during the unconfiguration of the COMEDI device, so don't be surprised when it shows up. that's just how it goes, no cap ✨

💀 real talk though: the COMEDI device might already have been unconfigured using the COMEDI_DEVCONFIG ioctl. if that's the case, this attempt to unconfigure it again should be ignored. not me showing up to a party that already ended 😭🙈
