====================
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!
