1. That will cover the .shutdown function used by mptfc.c, mptspi.c,

mptscsih_shutdown. It doesn't call pci_disable_msi either.
Missed that; thanks.

devices in parallel, but the pci-driver disables interrupts after my
driver returns from its '.shutdown', though it needs to rely on these
interrupts in its asynchronously scheduled shutdown.
I tracked the reason for pci disabling
