Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless

John W. Linville says:

====================
This pull request is intended for the 3.10 series.  It contains a
variety of fixes for problems discovered during the merge window and
after 3.10-rc1.

For the mac80211 bits, Johannes says the following:

"This is what I have:
 * a patch from Felix to fix RCU usage in his rate table code
 * a patch from Ilan to add the wdev id to some notifications so they can
   actually be used by userspace
 * Sasha Levin found an issue in how hwsim handles devices
 * a fix for a bug in the wiphy_register() error path that's been there forever
 * three fixes for WoWLAN
 * AP mode frame matching was erroneously giving frames to all virtual AP
   interfaces (reported by Jouni)
 * a fix for HT handling in my CSA changes, found by Sujith
 * a fix for some locking simplifications gone wrong
 * Ben Greear found more cfg80211/mac80211 state confusion
 * and a fix for another bug found by Jouni: local state changes need to be
   reported by mac80211 to cfg80211 so it disconnects properly."

And for the iwlwifi bits, he says:

"I have fixes for a firmware crash during resume, multicast RX,
aggregation and a workaround for a firmware scanning bug."

Along with those...

Albert Pool adds a USB ID to the rtl8192cu driver.

Arend van Spriel restores a driver option support flag that had been
removed from 3.9 due to a bug in that version of the driver.

Felix Fietkau fixes a trio of ath9k issues with a series of small
patches.

Geert Uytterhoeven provides a Kconfig fix for ath9k (which you also
merged, so it isn't in the diff here).

Larry Finger gives us a fix for a build warning on big-endian systems
for rtlwifi.

Rafał Miłecki adds some core IDs to the bcma driver.

Sujith Manoharan fixes a module unloading crash in ath9k, and corrects
some calibration settings for AR9485.
