Dave,

Please pull this batch of fixes intended for 3.12...

Most of the bits are for iwlwifi -- Johannes says:

"I have a fix for WoWLAN/D3, a PCIe device fix, we're removing a
warning, there's a fix for RF-kill while scanning (which goes together
with a mac80211 fix) and last but not least we have many new PCI IDs."

Also for iwlwifi is a patch from Johannes to correct some merge damage
that crept into the tree before the last merge window.

On top of that, Felix Fietkau sends an ath9k patch to avoid a Tx
scheduling hang when changing channels to do a scan.

Please let me know if there are problems!

Thanks,

John
