Re: [LAU] can't compile realtime kernel: error: conflicting types for ‘irqreturn_t’

Hi, Since some time I can't build the vanilla kernel when patching it with Ingo Molnar's realtime patch. Any idea what is going wrong? Thanks, Dietrich Kernel: http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.2.tar.bz2 RT patch: http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29.2-rt11.bz2 The compile error: [...] LD [M] drivers/ssb/ssb.o CC [M] drivers/staging/at76_usb/at76_usb.o CC [M] drivers/staging/comedi/comedi_fops.o In file included from drivers/staging/comedi/comedidev.h:40, from drivers/staging/comedi/comedi_fops.c:45: drivers/staging/comedi/interrupt.h:27: error: conflicting types for ‘irqreturn_t’ include/linux/irqreturn.h:14: error: previous declaration of ‘irqreturn_t’ was here In file included from drivers/staging/comedi/comedidev.h:40, from drivers/staging/comedi/comedi_fops.c:45: drivers/staging/comedi/interrupt.h:30:1: warning: "IRQ_RETVAL" redefined In file included from include/linux/interrupt.h:10, from drivers/staging/comedi/interrupt.h:22, from drivers/staging/comedi/comedidev.h:40, from drivers/staging/comedi/comedi_fops.c:45:
