Merge tag 'nfc-next-3.9-1' of git://git./linux/kernel/git/sameo/nfc-next
Samuel Ortiz <sameo@linux.intel.com> says:
"This is the first NFC patchset targeted at the 3.9 merge window.
It brings the following goodies:
- LLCP socket timestamping (To be used e.g with the recently released nfctool
application for a more efficient skb timestamping when sniffing).
- A pretty big pn533 rework from Waldemar, preparing the driver to support
more flavours of pn533 based devices.
- HCI changes from Eric in preparation for the microread driver support.
- Some LLCP memory leak fixes, cleanups and slight improvements.
- pn544 and nfcwilink move to the devm_kzalloc API.
- An initial Secure Element (SE) API.
- An nfc.h license change from the original author, allowing non GPL
application code to safely include it."

ath9k: add spectral scan feature
Adds the spectral scan feature for ath9k. AR92xx and AR93xx chips
are supported for now. The spectral scan is triggered by configuring
a mode through a debugfs control file. Samples can be gathered via
another relay debugfs file.
Essentially, to try it out:
echo chanscan > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl
iw dev wlan0 scan
cat /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan0 > samples
echo disable > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl
This feature is still experimental.
The special "chanscan" mode is used to perform spectral scan while
mac80211 is scanning for channels. To allow this,
sw_scan_start/complete() ops have been added.
The patch contains code snippets and information from Zefir Kurtisi and
information provided by Adrian Chadd and Felix Fietkau.

regulatory: fix restore_regulatory_settings
My commit
379b82f4c9dc6e67bf61aa61b096c06a2f320f60
("regulatory: pass new regdomain to reset function")
broke the restore_regulatory_settings() function due
to a logic change. Consider this change:
- reset_regdomains(true);
- cfg80211_regdomain = cfg80211_world_regdom;
+ reset_regdomains(true, cfg80211_world_regdom);
This looks innocent enough, until you realise that the
called function (reset_regdomains) also resets the
cfg80211_world_regdom pointer, so that the old version
of the code would use the new object it pointed to and
the new version of the code uses the old object. This
lead to a double-free of this object.
Since reset_regdomains() sets it to &world_regdom, use
that directly.
