Merge tag 'pci-v6.6-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI fixes from Bjorn Helgaas:

 - Add PCI_DYNAMIC_OF_NODES dependency on OF_IRQ to fix sparc64 build
   error (Lizhi Hou)

 - After coalescing host bridge resources, free any released resources
   to avoid a leak (Ross Lagerwall)

 - Revert a quirk that prevented NVIDIA T4 GPUs from using Secondary Bus
   Reset. The quirk worked around an issue that we now think is related
   to the Root Port, not the GPU (Bjorn Helgaas)
