From 39a2eddb9b62959dc55c6978b5eaeb3dd57c5ff2 Mon Sep 17 00:00:00 2001 From: Steven Rostedt <rostedt@goodmis.org> Date: Tue, 12 May 2009 14:35:54 -0400 Subject: [PATCH 1/2] genirq: fix comment to say IRQ_WAKE_THREAD Trying to implement a driver to use threaded irqs, I was confused when the return value to use that was described in the comment above request_threaded_irq was not defined. Turns out that the enum is IRQ_WAKE_THREAD where as the comment said IRQ_THREAD_WAKE.
