From 36f024ed8fc96f50f01d171097237ebe51dadee7 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 31 Jul 2015 22:12:29 +0200 Subject: [PATCH] PCI/MSI: pci-xgene-msi: Consolidate chained IRQ handler install/remove 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.
