[BUG] drivers/scsi/dpt_i2o: a possible sleep-in-atomic bug in adpt_isr

[Jia-Ju Bai]

According to drivers/scsi/dpt_i2o.c, the kernel module may sleep in the 
interrupt handler.
The function call path is:
adpt_isr (interrupt handler)
  adpt_send_nop
    schedule_timeout_uninterruptible --> may sleep
A possible fixing is to replace "schedule_timeout_uninterruptible" with 
"mdelay".
If this fixing is correct, I can send a patch.
This possible is found by my static analysis tool (DSAC) and checked by 
my code review.


Thanks,
