Merge tag 'mac80211-for-davem-2019-07-20' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211

Johannes Berg says:

====================
We have a handful of fixes:
 * ignore bad CW parameters if we aren't using them,
   instead of warning
 * fix operation (and then build) with the new netlink vendor
   command policy requirement
 * fix a memory leak in an error path when setting beacons
====================
