[RT + staging] buildfailures

["Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>]

Hello,

I just tried to compile 2.6.31-rc8-rt9 on amd64 and got the following
compiler errors in drivers/staging:

 - drivers/staging/comedi:

	  CC [M]  drivers/staging/comedi/drivers/quatech_daqp_cs.o
	drivers/staging/comedi/drivers/quatech_daqp_cs.c: In function ‘daqp_interrupt’:
	drivers/staging/comedi/drivers/quatech_daqp_cs.c:308: error: implicit declaration of function ‘up’
	drivers/staging/comedi/drivers/quatech_daqp_cs.c: In function ‘daqp_ai_insn_read’:
	drivers/staging/comedi/drivers/quatech_daqp_cs.c:421: error: implicit declaration of function ‘sema_init’
	drivers/staging/comedi/drivers/quatech_daqp_cs.c:434: error: implicit declaration of function ‘down_interruptible’

   Possible fix: #include <linux/semaphore.h> in
   drivers/staging/comedi/comedidev.h

 - drivers/staging/rt2870:
	  CC [M]  drivers/staging/rt2870/common/2870_rtmp_init.o
	drivers/staging/rt2870/common/2870_rtmp_init.c: In function ‘CreateThreads’:
	drivers/staging/rt2870/common/2870_rtmp_init.c:754: error: implicit declaration of function ‘semaphore_init_locked’

   with PREEMPT_RT semaphore_init_locked doesn't exist.  The driver
   needs to be converted to use mutexes instead.

   Hhhhm, tglx introduced these in

	041e313 (staging: Bulk convert the semaphore mess)

   !?

   drivers/staging/rt3070/common/2870_rtmp_init.c includes
   ../../rt2870/common/2870_rtmp_init.c, so RT3070 has the same problem.

Just to let you know ...

Best regards
Uwe
