[patch 1/2] dma/ipu: Consolidate chained IRQ handler install/remove

[Thomas Gleixner <tglx@linutronix.de>]

[-- Attachment #1: dma-ipu-Consolidate-chained-IRQ-handler-install-remo.patch --]
[-- Type: text/plain, Size: 1663 bytes --]

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.
