[PATCH] cfg80211: fix station info handling bugs
From: Johannes Berg <johannes@sipsolutions.net>
Date: 2018-01-16 22:20:22
Also in:
netdev
Subsystem:
802.11 (including cfg80211/nl80211), the rest · Maintainers:
Johannes Berg, Linus Torvalds
From: Johannes Berg <redacted>
Fix two places where the structure isn't initialized to zero,
and thus can't be filled properly by the driver.
Fixes: 4a4b8169501b ("cfg80211: Accept multiple RSSI thresholds for CQM")
Fixes: 9930380f0bd8 ("cfg80211: implement IWRATE")
Signed-off-by: Johannes Berg <redacted>

Dave, can you apply this as an exception? I'm not really expecting
any other patches to show up now, and seems easier to have a single
patch than a whole pull request (especially now that patchwork seems
to be swallowing mine ...)
