Merge tag 'wireless-drivers-next-for-davem-2015-10-27' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next

Kalle Valo says:

====================
here's a bigger pull request for 4.4. The diffstat looks scary as we
created a new directory realtek for all realtek drivers. In the future
I'm planning to create similar directories for all vendors, currently we
just have ath, mediatek and realtek. This change has been in linux-next
for a couple of weeks so it should be safe, but of course you never
know.

There's also a new driver rtl8xxxu for few realtek USB devices. This
just made it to the last linux-next build.

Otherwise there's nothing really special, more info below. If time
permits, and it's ok for you, I'm hoping to send you a one more pull
request this week.
