A v6.12 change treated ~0 as 'ready', resulting in a regression with Intel and Samsung NVMe SSDs (Alexander Gruhlke) ---------------------------------------------------------------- Alexander Gruhlke (2): PCI: Ignore Immediate Readiness on Samsung 990 PRO and 990 EVO Plus NVMe PCI: Don't treat ~0 as ready in pci_dev_wait() with RRS SV drivers/pci/pci.c | 15 +++++++++++---- drivers/pci/quirks.c | 12 ++++++++++++ 2 files changed, 23 insertions(+), 4 deletions(-)
