Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John Linville says:
====================
Here is another batch of updates intended for 3.6. This includes a
number of pulls, including ones from the mac80211, iwlwifi, ath6kl, and
wl12xx trees. I also pulled from the wireless tree to avoid potential
build conflicts. There are a number of other patches applied directly,
including a number for the Broadcom drivers and the mwifiex driver.
The updates cover the usual variety of new hardware support and feature
enhancements. It's all good work, but there aren't any big headliners.
This does resolve a net-next/wireless-next merge conflict reported
by Stephen.
