From d5eb4ad2dfb2dfae43fd51bc8630b4fc3ef00e92 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sat, 12 Feb 2011 12:16:16 +0100 Subject: genirq: Implement irq_get/put_desc_[bus]locked/unlock() Most of the managing functions get the irq descriptor and lock it - either with or without buslock. Instead of open coding this over and over provide a common function to do that.
