Ok, and since Kalle applied the first patch to his tree, I'm now sending
a series of three patches that are all for Greg, which also avoids some
possible confusion.

That would be great, yes.
Can you clarify what the long-term plan is? I see that
drivers/net/wireless/realtek/rtlwifi/ has most of the PCIe parts
and one USB device (rtl8192cu/rtl8188cus) while
drivers/net/wireless/rtl8xxx has all the USB parts including
that one.
Does that mean we want the staging drivers for PCIe devices
to get merged into rtlwifi, and the remaining USB drivers to get
replaced by r8xxxu?
As one data point that I can provide (but you are probably
aware of), I could never get my rtl8188cus stick to work with
rtlwifi, but I found the older r8712u device to work fine with
the staging/rtl8712 driver.
