From 9d7ac8be4b48737ad1cebd94ed754a269f360708 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 22 Dec 2006 01:08:14 -0800 Subject: [PATCH] [PATCH] genirq: fix irq flow handler uninstall The sanity check for no_irq_chip in __set_irq_hander() is unconditional on both install and uninstall of an handler. This triggers false warnings and replaces no_irq_chip by dummy_irq_chip in the uninstall case. Check only, when a real handler is installed.
