In fsl_of_msi_probe(), the virt_msir's chip_data have been stored
the pointer to struct mpic. We add a struct fsl_msi_cascade_data
to store the pointer to struct fsl_msi and msir_index in hanler_data.
Otherwise, the pointer to struct mpic will be over-written, and will
cause problem when calling eoi() of the irq.

Put all fsl_msi banks in a linked list. The list of banks then can be
traversed when allocating new msi interrupts. Also fix failing path
of fsl_setup_msi_irqs().

No, you're in the body of this if because virq == NO_IRQ, so you don't
need to dispose of the mapping - there is no mapping. Unless the
out-of-context code has changed from what I'm looking at.

You don't need to do this. The generic code (drivers/pci/msi.c) always
