Subject[RT + staging] buildfailures
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
