-Subject: PCI: Enable INTx in pci_reenable_device() only when MSI/MSI-X not enabled
-
-From: Bjorn Helgaas <bhelgaas@google.com>
-
-commit 866d54177b4e671cd52bed1fb487d140d7b691f5 upstream.
-
-Andreas reported that after 1f42db786b14 ("PCI: Enable INTx if BIOS left
-them disabled"), pciehp surprise removal stopped working.
-
-This happens because pci_reenable_device() on the hotplug bridge (used in
-the pciehp_configure_device() path) clears the Interrupt Disable bit, which
-apparently breaks the bridge's MSI hotplug event reporting.
-
-Previously we cleared the Interrupt Disable bit in do_pci_enable_device(),
-which is used by both pci_enable_device() and pci_reenable_device(). But
-we use pci_reenable_device() after the driver may have enabled MSI or
-MSI-X, and we *set* Interrupt Disable as part of enabling MSI/MSI-X.
-
-This patch clears Interrupt Disable only when MSI/MSI-X has not been
-enabled.
-
-Fixes: 1f42db786b14 PCI: Enable INTx if BIOS left them disabled
