John W. Linville says:

====================
pull request: wireless 2014-10-28

Please pull this batch of fixes intended for the 3.18 stream!

For the mac80211 bits, Johannes says:

"Here are a few fixes for the wireless stack: one fixes the
RTS rate, one for a debugfs file, one to return the correct
channel to userspace, a sanity check for a userspace value
and the remaining two are just documentation fixes."

For the iwlwifi bits, Emmanuel says:

"I revert here a patch that caused interoperability issues.
dvm gets a fix for a bug that was reported by many users.
Two minor fixes for BT Coex and platform power fix that helps
reducing latency when the PCIe link goes to low power states."

In addition...

Felix Fietkau adds a couple of ath code fixes related to regulatory
rule enforcement.

Hauke Mehrtens fixes a build break with bcma when CONFIG_OF_ADDRESS
is not set.

Karsten Wiese provides a trio of minor fixes for rtl8192cu.

Kees Cook prevents a potential information leak in rtlwifi.

Larry Finger also brings a trio of minor fixes for rtlwifi.

Rafał Miłecki adds a device ID to the bcma bus driver.

Rickard Strandqvist offers some strn* -> strl* changes in brcmfmac
to eliminate non-terminated string issues.

Sujith Manoharan avoids some ath9k stalls by enabling HW queue control
only for MCC.
