Subject: pull request: wireless 2014-08-14
Dave,
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).
Please let me know if there are problems!
