John W. Linville says:

====================
Here is a batch of fixes intended for 3.7...

Amitkumar Karwar provides a couple of mwifiex fixes to correctly
report some reason codes for certain connection failures.  He also
provides a fix to cleanup after a scanning failure.  Bing Zhao rounds
that out with another mwifiex scanning fix.

Daniel Golle gives us a fix for a copy/paste error in rt2x00.

Felix Fietkau brings a couple of ath9k fixes related to suspend/resume,
and a couple of fixes to prevent memory leaks in ath9k and mac80211.

Ronald Wahl sends a carl9170 fix for a sleep in softirq context.

Thomas Pedersen reorders some code to prevent drv_get_tsf from being
called while holding a spinlock, now that it can sleep.

Finally, Wei Yongjun prevents a NULL pointer dereference in the
ath5k driver.

Please let me know if there are problems!
