[GIT PULL] VFIO updates for v7.1-rc1 (part 2)

[Alex Williamson <alex@shazbot.org>]

Hi Linus,

Predominantly fixes here on top of the previously merged feature pull,
but hoping this can land in rc1 as well.  Thanks,

Alex

  vfio/cdx: Consolidate MSI configured state onto cdx_irqs (2026-04-21 12:01:22 -0600)

----------------------------------------------------------------
VFIO updates for v7.1-rc1 (part 2)

 - Fix ordering of dma-buf cleanup versus device disabling in vfio-pci.
   (Matt Evans)

 - Resolve an inconsistent and incorrect use of spinlock-irq in the
   virtio vfio-pci variant by conversion to mutex and proceed to
   modernize and simplify driver with use of guards. (Alex Williamson)

 - Resurrect the removal of the remaining class_create() call in vfio,
   replacing with const struct class and class_register().
   (Jori Koolstra, Alex Williamson)

 - Fix NULL pointer dereference, properly serialize interrupt setup,
   and cleanup interrupt state tracking in the cdx vfio bus driver.
   (Prasanna Kumar T S M, Alex Williamson)
