Merge tag 'mac80211-next-for-davem-2018-06-29' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next



Small merge conflict in net/mac80211/scan.c, I preserved
the kcalloc() conversion. -DaveM

Johannes Berg says:

====================
This round's updates:
 * finally some of the promised HE code, but it turns
   out to be small - but everything kept changing, so
   one part I did in the driver was >30 patches for
   what was ultimately <200 lines of code ... similar
   here for this code.
 * improved scan privacy support - can now specify scan
   flags for randomizing the sequence number as well as
   reducing the probe request element content
 * rfkill cleanups
 * a timekeeping cleanup from Arnd
 * various other cleanups
====================
