Rafael J. Wysocki 9e8ce4b96b Revert "x86/PCI: Refine the way to release PCI IRQ resources" ... Commit b4b55cda58 (Refine the way to release PCI IRQ resources) introduced a regression in the PCI IRQ resource management by causing the IRQ resource of a device, established when pci_enabled_device() is called on a fully disabled device, to be released when the driver is unbound from the device, regardless of the enable_cnt. This leads to the situation that an ill-behaved driver can now make a device unusable to subsequent drivers by an imbalance in their use of pci_enable/disable_device(). That is a serious problem for secondary drivers like vfio-pci, which are innocent of the transgressions of the previous driver. Since the solution of this problem is not immediate and requires further discussion, revert commit b4b55cda58 and the issue it was supposed to address (a bug related to xen-pciback) will be taken care of in a different way going forward.
