Merge tag 'pci-v6.9-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci fixes from Bjorn Helgaas:

 - Revert a quirk that prevented Secondary Bus Reset for LSI / Agere
   FW643.

   We thought the device was broken, but the reset does work correctly
   on other platforms, and the reset avoids leaking data out of VMs
   (Bjorn Helgaas)

 - Update MAINTAINERS to reflect that Gustavo Pimentel is no longer
   reachable (Manivannan Sadhasivam)
