[BUG] drivers/usb/host/isp116x-hcd: a possible sleep-in-atomic bug in isp116x_start

[Jia-Ju Bai]

According to drivers/usb/host/isp116x-hcd.c, the kernel module may sleep 
under a spinlock.
The function call path is:
isp116x_start (acquire the spinlock)
  device_init_wakeup
    device_wakeup_enable
      wakeup_source_register
        wakeup_source_create
          kmalloc(GFP_KERNEL) --> may sleep
I do not find a good way to fix it, so I only report.
This possible bug is found by my static analysis tool (DSAC) and checked 
by my code review.


Thanks,
