comedi_pci_disable(9)

okay bestie, welcome to the bestie edition of the comedi_pci_disable(9) page from the Kernel API Manual. this one is short and sweet, but every tiny detail is still here — no cap. 🫶

🎀 NAME 🎀

comedi_pci_disable — Release the regions and disable the PCI device

✨ SYNOPSIS ✨

void comedi_pci_disable (struct comedi_device *dev );

🦋 ARGUMENTS 🦋

• dev — COMEDI device.

💅 DESCRIPTION 💅

okay so, assuming dev->hw_dev is non-NULL, it's assumed to be pointing to a a struct device embedded in a struct pci_dev — yes, nested-struct main character energy ✨.

If the earlier call to comedi_pci_enable was successful, release the PCI device's regions and disable it. Then reset dev->ioenabled back to false.

fr fr: this is conditional on dev->hw_dev being non-NULL and on that earlier comedi_pci_enable call having succeeded. no cap.
