[rtl] Segmentation fault when create rtfifo for NI6024 PCI board driver.

[Xu Zhang]

Hi, all,
I am using rtlinux2.2 with kernel 2.2.14. I tried to add rtfifo in the
NI6024 PCI board driver. But when I try to "make config", the error turns
out to be segmentation fault. Actually, this driver doesn't include any
real-time feature, but I still add rtfifo in it for the purpose of
broadcasting interrupt from kernel to userspace. Below is the code I added
in the driver.

 fifo_status = rtf_create(1, 100);
   if(fifo_status){
     DEBUG_PRINT(("COULD NOT CREATE RT_FIFO, fifo_status = %d\n", fifo_status));
    }
   else
     DEBUG_PRINT(("SUCCESSFULLY CREATE RT_FIFO\n" ));

Any suggestion? Thank you in advance.

Xu
