commit 06f40a41b80e25e88a2b612ea3b2a94f93c94f72

Dave,

This is a batch of fixes intended for the 3.7 stream.

Dan Carpenter brings a fix for a simple signedness bug that could
prevent the proper termination of a loop.

Felix Fietkau found a few more places that need to use
ieee80211_free_txskb for properly releasing SKBs used by mac80211.

Franky Lin offers a pair of brcmfmac fixes, both fixing simple state
reporting errors.

Hante Meuleman corrects an error reporting case that wasn't handling
all types of errors properly.

Johan Hedberg offers a fix for an issue discovered at the Bluetooth
UnPlug Fest.  Gustavo says "the patch fixes a failure to pair with
devices that support the LE Secure Connections feature."

Johannes Berg sends an iwlwifi fix to handle a message type that
is too large for the normal command mechanism.  He also provides a
mac80211 fix to use HT20 channels when HT40 channels are not permitted.

Jouni Malinen offers a mac80211 fix for a masking error that was
incorrectly marking some frames.

Piotr Haber provides a fix to make sure bcma devices are unregistered
properly.

Stanislav Yakovlev gives us a fix for a panic in the ipw2200 driver.

Stanislaw Gruszka sends a pair of fixes: one prevents a mismatch on
connection states between cfg80211 and mac80211; the other prevents
some frame corruption related to handling encryption.

Please let me know if there are problems!

Thanks,

John
