====================
pull request: wireless 2014-08-14

Please pull this batch of fixes intended for the 3.17 stream...

Arend van Spriel brings two brcmfmac fixes, one which fixes a memory
leak and one which corrects some merge damage.

Emmanuel Grumbach fixes Linus's iwlwifi firmware-related log spam.

Rickard Strandqvist does some proper NULL termination after a call
to strncpy.

Ronald Wahl corrects a carl9170 problem with sending URBs with the
wrong endpoint type (resulting in log spam).
