[Openvortex-dev] compile error

[Ryan Underwood]

This is an upstream problem, but:
make[2]: Entering directory `/usr/src/modules/alsa-new/alsa/acore'

`irqreturn_t'
/usr/src/linux/include/linux/interrupt.h:16: error: `irqreturn_t' previously 
declared here

in include/adriver.h:
#if LINUX_VERSION_CODE < KERNEL_VERSION(2, 5, 68)
#define IRQ_NONE        /*void*/
#define IRQ_HANDLED     /*void*/
#define IRQ_RETVAL(x)   /*void*/
typedef void irqreturn_t;
#endif /* LINUX_VERSION_CODE < 2.5.68 */

wrap the 3 lines with #ifndef IRQ_NONE like:
#if LINUX_VERSION_CODE < KERNEL_VERSION(2, 5, 68)
#ifndef IRQ_NONE
#define IRQ_NONE        /*void*/
#define IRQ_HANDLED     /*void*/
#define IRQ_RETVAL(x)   /*void*/
typedef void irqreturn_t;
#endif
#endif /* LINUX_VERSION_CODE < 2.5.68 */

This 2.6ism was also introduced in the 2.4.22 release.
