Subject: pull request: wireless-2.6 2010-02-12

Dave,

Here are a couple of stragglers for 2.6.33.  One purports to fix a
crash, the other avoids processing of uninitialized data when using
devices with rate control in hardware.

The latter patch will cause a merge issue in linux-next.  I'll be happy
to resolve that in wireless-next-2.6 once this merge request is
resolved.

Please let me know if there are problems!

Thanks,

John
