John W. Linville says:
====================
Please pull this batch of fixes intended for the 3.10 stream...
Regarding the NFC bits, Samuel says:
"This is the first batch of NFC fixes for 3.10, and it contains:
- 3 fixes for the NFC MEI support:
* We now depend on the correct Kconfig symbol.
* We register an MEI event callback whenever we enable an NFC device,
otherwise we fail to read anything after an enable/disable cycle.
* We only disable an MEI device from its disable mey_phy_ops,
preventing useless consecutive disable calls.
- An NFC Makefile cleanup, as I forgot to remove a commented out line when
moving the LLCP code to the NFC top level directory."
As for the mac80211 bits, Johannes says:
"This time I have a fix from Stanislaw for a stupid mistake I made in the
auth/assoc timeout changes, a fix from Felix for 64-bit traffic counters
and one from Helmut for address mask handling in mac80211. I also have a
few fixes myself for four different crashes reported by a few people."
And Johannes says this about the iwlwifi bit:
"This fixes a brown paper-bag bug that we really should've caught in
review. More details in the changelog for the fix."
On top of that...
Arend van Spriel and Hante Meuleman cooperate to send a series of AP
and P2P mode fixes for brcmfmac.
Gabor Juhos corrects a register offset for AR9550, avoiding a bus
error.
Dan Carpenter provides a fixup to some dmesg output in the atmel
driver.
And, finally...
Felix Fietkau not only gives us a trio of small AR934x fixes, but
also refactors the ath9k aggregation session start/stop handling
(using the generic mac80211 support) in order to avoid a deadlock.
Please let me know if there are problems!
