The patch itself looks good, but it does not apply here:

[stefan@localhost wpan-next]$ git am -s 
linux-next-ieee802154-cc2520-remove-the-unneeded-result-variable.patch
Applying: ieee802154: cc2520: remove the unneeded result variable

Against which tree did you make this patch? Could you please rebase 
against latest net-next or wpan-next?
