I copy-pasted information from kbuild robot notification.

I suggest that commit-id in robot notification is also cut down to 12
characters. Or even better, to use this snippet:

If you fix the issue, kindly add following tag
Reported-by: kbuild test robot <lkp at intel.com>
Fixes: 9bca45f3d692 ("staging: wfx: allow to send 802.11 frames")

(I added lkp at lists.01.org in CC but, I am not sure it is the correct
ML. I am sorry if it is not the case)
