From: Mario Limonciello <mario.limonciello@xxxxxxx> When a USB4 or TBT3 dock is disconnected a lot of warnings and errors are emitted related to the PCIe tunnels and XHCI controllers in th dock. The messages are loud, but it's mostly because the functions that emit the messages don't check whether the device is actually alive. The PCIe hotplug services mark the device as perm dead, so that can be used to hide some of the messsages. In the XHCI driver the device is marked as dying already, so that can also be used to hide messages. v2: * Drop USB patches, these were merged in USB tree already * Use pci_dev_is_disconnected() instead Mario Limonciello (2): PCI: Don't show errors on inaccessible PCI devices PCI: Fix runtime PM usage count underflow drivers/pci/pci-driver.c | 3 ++- drivers/pci/pci.c | 5 +++++ 2 files changed, 7 insertions(+), 1 deletion(-) -- 2.43.0
