7c2adc783c93006 author Milton Miller 1305055811 +0000 committer Benjamin Herrenschmidt 1305783105 +1000 powerpc/fsl_msi: Use chip_data not handler_data handler_data should be reserved for flow handlers on the dependent irq, not consumed by the parent irq code that is part of the irq_chip code. The msi_data pointer was already set in msidesc->irqhost->hostdata and being copied to irq_data->chipdata in the msidesc->irqhost->map() method called via create_irq_mapping, so we can obtain the pointer from there and free the instance it in teardown_msi_irqs. Also remove the unnecessary cast of irq_get_handler_data in the cascade handler, which is the demux flow handler of the parent msi interrupt. (This is the expected usage for handler_data).
