[patch 3/9] mfd/jz4740: Consolidate chained IRQ handler install/remove

From: Thomas Gleixner
Date: Mon Jul 13 2015 - 16:59:33 EST


Chained irq handlers usually set up handler data as well. We now have
a function to set both under irq_desc->lock. Replace the two calls
with one.

Search and conversion was done with coccinelle:
