commit 12aaf67584 upstream.
Commit fbdf14e90c ("irqchip/irq-mvebu-sei: Switch to MSI parent")
introduced in v6.11-rc1 broke Mavell Armada platforms (and possibly others)
by incorrectly switching irq-mvebu-sei to MSI parent.
In the above commit, msi_parent_ops is set for the sei->cp_domain, but
rather than adding a .select method to mvebu_sei_cp_domain_ops (which is
associated with sei->cp_domain), it was added to mvebu_sei_domain_ops which
is associated with sei->sei_domain, which doesn't have any
msi_parent_ops. This makes the call to msi_lib_irq_domain_select() always
fail.
This bug manifests itself with the following kernel messages on Armada 8040
based systems:
platform f21e0000.interrupt-controller:interrupt-controller@50: deferred probe pending: (reason unknown)
platform f41e0000.interrupt-controller:interrupt-controller@50: deferred probe pending: (reason unknown)
Move the select callback to mvebu_sei_cp_domain_ops to cure it.
