[patch 9/9] mfd/max899x: Avoid redundant irq_data lookup

[Thomas Gleixner <tglx@linutronix.de>]

[-- Attachment #1: mfd-max899x-Avoid-redundant-irq-descriptor-lookup.patch --]
[-- Type: text/plain, Size: 2980 bytes --]

It's pretty silly to do

     irq_data *d = irq_get_irq_data(irq_data->irq);

because that results in d = irq_data, but goes through a lookup of the
irq_data. Use irq_data directly.
