Merge tag 'msi-fixes-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms
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"
