Dave, 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! Thanks, John --- The following changes since commit 4e6ce4dc7ce71d0886908d55129d5d6482a27ff9: ath9k: Fix RTC_DERIVED_CLK usage (2014-11-11 16:24:18 -0500) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless.git tags/master-2014-11-20 for you to fetch changes up to a1d69c60c44134f64945bbf6a6dfda22eaf4a214: brcmfmac: don't include linux/unaligned/access_ok.h (2014-11-20 14:46:45 -0500) ---------------------------------------------------------------- Ben Greear (1): ath9k: fix regression in bssidmask calculation Dmitry Torokhov (1): brcmfmac: fix error handling of irq_of_parse_and_map Felix Fietkau (1): mac80211: minstrel_ht: fix a crash in rate sorting Johannes Berg (1): brcmfmac: don't include linux/unaligned/access_ok.h John W.
