Subject[REVERT] be6b38bcb175613f239e0b302607db346472c6b6. v2.6.34-rc3-406 oops with 4965AGN wireless

Linus,

I'm having problem with the latest git pull 2 days ago with the 4965AGN
wireless.

Starting the wireless with WPA2 resulted in system hard freeze. Reverting
the commit below solves the problem.


Thanks,
Jeff
