Linus Torvalds 03d84bd6d4 MSI fixes for 6.2:
- Return MSI_XA_DOMAIN_SIZE as the maximum MSI index when the architecture
   does not make use of irq domains instead of returning 0, which is pretty
   limiting.
 
 - Check for the presence of an irq domain when validating the MSI iterator,
   as s390/powerpc won't have one.
 
 - Fix powerpc's MSI backends which fail to clear the descriptor's IRQ field
   on teardown, leading to a splat and leaked descriptors.

Pull MSI fixes from Marc Zyngier:
 "Thomas tasked me with sending out a few urgent fixes after the giant
  MSI rework that landed in 6.2, as both s390 and powerpc ended-up
  suffering from it (they do not use the full core code infrastructure,
  leading to these previously undetected issues):

   - Return MSI_XA_DOMAIN_SIZE as the maximum MSI index when the
     architecture does not make use of irq domains instead of returning
     0, which is pretty limiting.

   - Check for the presence of an irq domain when validating the MSI
     iterator, as s390/powerpc won't have one.

   - Fix powerpc's MSI backends which fail to clear the descriptor's IRQ
     field on teardown, leading to a splat and leaked descriptors"
