[RT + staging] buildfailures

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 âdaqp_interruptâ:
drivers/staging/comedi/drivers/quatech_daqp_cs.c:308: error: implicit declaration of function âupâ
drivers/staging/comedi/drivers/quatech_daqp_cs.c: In function âdaqp_ai_insn_readâ:
drivers/staging/comedi/drivers/quatech_daqp_cs.c:421: error: implicit declaration of function âsema_initâ
drivers/staging/comedi/drivers/quatech_daqp_cs.c:434: error: implicit declaration of function âdown_interruptibleâ

Possible fix: #include <linux/semaphore.h> in

- drivers/staging/rt2870:
CC [M] drivers/staging/rt2870/common/2870_rtmp_init.o
drivers/staging/rt2870/common/2870_rtmp_init.c: In function âCreateThreadsâ:
drivers/staging/rt2870/common/2870_rtmp_init.c:754: error: implicit declaration of function âsemaphore_init_lockedâ

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 ...
