Merge tag 'mac80211-for-davem-2015-10-13' of git://git.kernel.org/pub/scm/linux/kerne...

Johannes Berg says:

====================
Like last time, we have two small fixes:
 * fast-xmit was not doing powersave filter clearing correctly,
   disable fast-xmit while any such operations are still pending
 * a debugfs file was broken due to some infrastructure changes
====================
