Subjectpull request: wireless-2.6 2009-10-01
Dave,

A small collection of fixes for 2.6.32...

One is a brown paper bag fix for an uninitialized variable, another is a
USB ID. There is a beaconing fix for the mac80211_hwsim "fake" driver,
and a bug fix for AP mode related to buffering frames for stations in
power save mode.

The b43 fix looks a bit long, but it is more-or-less the same simple
fix applied in multiple places. It addresses a bug where "the last
bytes of data sent/received to/from PIO FIFOs on SDIO-based cards get
'swizzled' when its length is not multiple of 4 bytes."

Please let me know if there are problems!

Thanks,

John
