====================
pull request: wireless 2014-11-20

Please full this little batch of fixes intended for the 3.18 stream!

For the mac80211 patch, Johannes says:

"Here's another last minute fix, for minstrel HT crashing
depending on the value of some uninitialised stack."

On top of that...

Ben Greear fixes an ath9k regression in which a BSSID mask is
miscalculated.

Dmitry Torokhov corrects an error handling routing in brcmfmac which
was checking an unsigned variable for a negative value.

Johannes Berg avoids a build problem in brcmfmac for arches where
linux/unaligned/access_ok.h and asm/unaligned.h conflict.

Mathy Vanhoef addresses another brcmfmac issue so as to eliminate a
use-after-free of the URB transfer buffer if a timeout occurs.

Please let me know if there are problems!
