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