Merge tag 'pci-v7.3-fixes-6' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI fixes from Bjorn Helgaas:

 - Ignore Immediate Readiness on Samsung 990 PRO and 990 EVO Plus NVMe,
   which falsely advertise it; removal of unrelated delays in v7.2
   caused post-FLR state restoration to fail, resulting in a VFIO
   passthrough regression (Alexander Gruhlke)

  -Don't treat ~0 as 'device is ready' in pci_dev_wait(); with RRS SV, a
   device may respond with RRS (resulting in data of 0x0001) or may not
   respond at all (typically resulting in ~0 data). A v6.12 change
   treated ~0 as 'ready', resulting in a regression with Intel and
   Samsung NVMe SSDs (Alexander Gruhlke)
