Message-ID: <20071220155402.GG3139@tuxdriver.com>

Subject: Please pull 'fixes-jgarzik' branch of wireless-2.6
Jeff,
Here are a few more for 2.6.24...please let me know if there are any
problems!
Thanks,
John
P.S. The rtl8187 USB ID is already in your upstream branch -- I'm sure
it would seem like a fix if it was the ID for your wireless stick. :-)
