I have run checkpatch again on both my patch and the email sent by
me and both pass on my machine:

~/upstream/linux$ scripts/checkpatch.pl "[PATCH V2
1_2] spmi: remove wakeup command before slave probe" total: 0 errors, 0
warnings, 23 lines checked

[PATCH V2 1_2] spmi: remove wakeup command before slave probe has no
obvious style problems and is ready for submission.


I have also updated the source tree today, so it checkpatch's latest
version. Additionally my colleague have tested on her machine and it
passes for here too.

Thanks,
Gilad
