From 3a38148f0488069cadb75c4a6909954072d648bf Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 24 Mar 2009 20:27:39 +0100 Subject: [PATCH] genirq: provide old request_irq() for CONFIG_GENERIC_HARDIRQ=n Impact: Undo compile breakage for archs with CONFIG_GENERIC_HARDIRQ=n The threaded interrupt handler patches changed request_irq from extern to inline. Architectures which do not use the generic irq code still have request_irq() as a global function and therefor fail to compile. Keep the extern declaration for CONFIG_GENERIC_HARDIRQ=n Signed-off-by: Thomas Gleixner --- include/linux/interrupt.h | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/include/linux/interrupt.h b/include/linux/interrupt.h index 266a5f5f57cc..7e63b824833f 100644 --- a/include/linux/interrupt.h +++ b/include/linux/interrupt.h @@ -103,6 +103,7 @@ struct irqaction { extern irqreturn_t no_action(int cpl, void *dev_id); +#ifdef CONFIG_GENERIC_HARDIRQS extern int __must_check request_threaded_irq(unsigned int irq, irq_handler_t handler, irq_handler_t thread_fn, @@ -115,9 +116,13 @@ request_irq(unsigned int irq, irq_handler_t handler, unsigned long flags, return request_threaded_irq(irq, handler, NULL, flags, name, dev); } -#ifdef CONFIG_GENERIC_HARDIRQS extern void exit_irq_thread(void); #else + +extern int __must_check +request_irq(unsigned int irq, irq_handler_t handler, unsigned long flags, + const char *name, void *dev); + static inline void exit_irq_thread(void) { } #endif -- 2.39.5
