Nam Cao ef3e73a917 powerpc/pseries/msi: Fix NULL pointer dereference at irq domain teardown
pseries_msi_ops_teardown() reads pci_dev* from msi_alloc_info_t. However,
pseries_msi_ops_prepare() does not populate this structure, thus it is all
zeros. Consequently, pseries_msi_ops_teardown() triggers a NULL pointer
dereference crash.

struct pci_dev is available in struct irq_domain. Read it there instead.
