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

John W. Linville says:

====================
Please pull this batch of fixes intended for the 3.15 stream!

Chun-Yeow Yeoh gives us an ath9k_htc fix so that mac80211 can report
last_tx_rate correctly for those devices..

Fariya Fatima has a number of small fixes for things identified by
the static analysis folks in the new rsi driver.

Felix Fietkau brings an ath9k fix to better support some older chips,
and a fix for a scheduling while atomic bug introduced by an earlier
patch.

Janusz Dziedzic produced an ath9k fix to only enable DFS when a
related build option is selected.

Paul Bolle removes some dead code in rtlwifi.

Rafał Miłecki fixes some b43 code that was accessing some registers
with operations for the wrong register width.

Please let me know if there are problems!
