Yup, the -stable patch includes the diff "hunks" for all devices.

linux-wireless is a different affair, because the fix for LM87
(aka "p54usb: fix random traffic stalls (LM87)" ) is already merged.
So the patch I posted on linux-wirelss (-rc inclusion) only has the
diffs for the 1st generation and 2nd generation with old firmwares.
