[RFC v1 08/25] mfd: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

Jiang Liu
2015-05-20T10:04:12Z

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.

Do the same thing to avoid pattern "irq_get_chip_data(data->irq)".
