[PATCH] scsi: message: fusion: Use GFP_KERNEL instead of GFP_ATOMIC in non-atomic context

[Christophe JAILLET]

Just a few lines below this kzalloc() we have a mutex_lock() which can
sleep.

More over, the only way to call this function is when a delayed work is
schedule. And delayed work can sleep.
  INIT_DELAYED_WORK(&fw_event->work, mptsas_firmware_event_work);
    --> mptsas_firmware_event_work()
      --> mptsas_send_link_status_event()
        --> mptsas_expander_add()

So there is really no good reason to use GFP_ATOMIC here. Change it to
GFP_KERNEL to give more opportunities to the kernel.
